How often should I change the oil in my car?

Whilst car engine and oil technology has dramatically changed which resulted in increased service intervals from 5 thousand kilometers to 15 to 20 thousand kilometers.

Many car owners are unknowingly imposing upon themselves a false sense of security by assuming that their oil needs to be replaced at 15 or perhaps at 20 thousand kilometers. In this part of the world due to frequent short distance and stop and go city driving you should be servicing your car under severe service section.

Today most car’s engines can last if looked after properly at least a quarter million kilometers, and most will last twice as long.

Oil dilution from un-burned fuel, frequent cold start and water from the combustion process while driven frequently at short distances will damage the engine.

Most drivers don’t realize that the internal combustion engine needs at least twenty kilometers of driving to remove the blow by water and fuel from the motor oil which is the blood of the engine as we all know it.

Worth to note; Proper high quality oil filter is also equally important to keep all the precious internal mechanical components in great shape to decades or more. More info on oil filters…

Please also pay special attention to specific ACEA designation by each respective manufacturer of all the European automobiles.

Diesel Mercedes, diesel BMW?

The usual questions we get; What do you think? Should I buy a diesel or gas powered automobile?

To put it promptly a diesel powered automobile, car or SUV designed and meant for long distance driving only. They not meant to perform for short trips or daily errands, due to the extensive complex emission control systems on board.

Diesel car’s emission control system needs to be self  cleaned intermittently just like your oven at home. The diesel particulate filter needs to be regenerated periodically which should not be interrupted multiple times or the check engine light will be illuminated.

Most European cars or trucks hate short distance driving, due to the fact they are built for the Autobahn where it will be driven at high speed so it gets a so called proper circulation.

Proper circulation ensures that the motor oil stays clean and filtered same applies to the diesel particulate filter as well which in turn extends the life of the engine and emission components. We have numerous clients with extreme mileage because their cars are distance driven regularly.

Diesel equipped cars or trucks will only return their investment if driven extra long distances like someone is on the road and travels a lot in my calculations at least 40 thousand kilometers a year, otherwise it will not be economical at all in the long term.

What type of car should I buy?

My clients often ask me the question; What type of car should I buy? Mercedes, Porsche, BMW, maybe Mini Cooper? They say, since you (me) repair them you should know it best.

This is rather interesting question and there is not one fits all the answer. To make the right decision many different factors should be considered for instance the drivers age and financial situation at hand will make a big difference. The purpose or main use of the vehicle will also determine the type and model of the most suitable car for the drivers need.

To choose the right car there are many more additional considerations, like the main use will be commuting or local driving. Furthermore maintenance, repair costs and gas mileage should be also considered as well. So as you see, it is not an easy choice to pick the right car for most people.

There are so many different criteria, they are different for many drivers as is their needs. Suffice to say we have a little slogan we use;  “The bigger the wheels the bigger the bills”. It may sound funny but in short term it does apply in most cases.

According to my experience, a large SUV will be twice as costly as a sedan with a small engine. The least expensive a model is, the least it will cost in fuel in repairs and maintenance.

We try our best to advise and help to choose the right automobile so you and your family will be happy many years to come with their choice.

Oil change on today’s high tech ultra efficient cars

The relatively simple oil change on today’s high tech ultra efficient cars are anything but simple. For instance BMW has a bunch of numbers on their oil requirements on vastly  different engines. The oldest one is LL98 then, the next is LL01 there after came LL04 and the next would be LL14.

German long life synthetic mootor oilFuchs Motor Oils

There is an even newer one which, is only for the very latest engines, from 2017 and up.

Furthermore older M engines require a specific grade like 10/60.

Mercedes is quiet the same MB 229, 31-229, 51-229.5 is the three most common designation for late model engines.

In most cases the diesel oriented BMW LL04 can be used in the gas engines for limited distance (no longer than 15 thousand kilometers between oil changes). The LL01 or the LL98 oil is prohibited in the diesel engines due to zinc in those  motor oils. Ditto for Mercedes Benz the 229.5 oil is strictly gas engines only.

The 229.31-229.51 oils are diesel oriented but can be used in most gas engine Mercedes Benz vehicles, except AMG which must have the 229.5 oil specifically.

There is one more additional spec for MB but that only applies to a single engine which is a rarity so we leave that one out for now. The implications are huge for using the wrong oil in the wrong application which at least will damage the diesel particulate filter (in short form DPF) or in the case of a gas engine possible engine damage may occur, especially if the extended service intervals are used.

Liqui Moly Synthetic motor oilsLiqui Moly Lubricants

To make it more confusing Mercedes specifies a felt oil filter for extended oil changes. The original manufacturer is in most cases Mann & Hummel of Germany.

There are two more original filter manufacturer Hengst of Germany and Knecht Mahle of Austria. There is currently a new French manufacturer which is also original equipment manufacturer called Pureflux. Read more about oil filters.

The question we often get;  Can I get my oil changes done elsewhere other than the dealer? The answer is yes, definitely, however you need to pay special attention to detail and must document the type and make of the oil and the filter on the invoice, so there are no issues if the question asked in the future while your car is under warranty.

The next question is; Are there better oils available than what has been sold by the dealer organization?  The answer is yes definitely there are better oils available. In most cases they are mainly imported from Germany.  Canadian dealers are providing North American sourced motor oils. Currently BMW uses Shell – Pennzoil.  Mercedes prefers Mobil1 from Exxon Mobil or sometime Shell – Pennzoil.

Diesel Green Force from Liqui Moly

Liqui Moly’s Green Diesel Additive

Green Diesel Additive is an active substance with cleaning, dispersing and material-protective properties, matched to both proven and modern engines and operating supply requirements. The contained Lubricity Improver improves the lubricity of the fuel. The additive increases the cetane number and thereby improves the cold-start behaviour of any diesel engine. It reduces the typical diesel knocking and ensures a better power output. Colour indicators help detect the additive fuel safely.

A European Gas Station Chain developed a premium diesel fluid with this  LIQUI MOLY additive. The gas station fill this additive in their diesel fluid in order to sell this as premium fuel.

The addictive name is Diesel Green Force.  LIQUI MOLY’s logo is shown at every gas station and at every fuel pump from this chain.

This is a pioneer project, never before LIQUI MOLY  supplied a major gas station chain with additives for their fuel tanks. Many European Gas Station chains are owned by their competitors (Shell, BP) or have long-term obligations with them.

You can read more about LIQUI MOLY’s products at our  LIQUI MOLY’s lubrication page.

Turbocharged Engines

The new turbocharged engines are the mainstays of all late model automobiles as you may noticed lately, everywhere you look literally every manufacturer only produces turbo engines.

We used to associate turbo engines with performance cars or high performance machines. That is no longer the case, today every manufacturer switched to turbo chargers to literally downsize their engines and to boost their efficiency by reducing the pumping losses.

turbocharged BMW engine

6 Cylinder Turbocharged BMW Engine

Thanks to ever tightening emission and reduced fuel consumption regulations we live in a new turbo era.

There are a few things you need to remember, if you want to have your turbo charger to last.

You need to use the best possible motor oil and some additional precautions like after long drives or spirited driving, you should open your hood for a few minutes to allow the turbo charger to went all that heat out .

Yes, all of them has a additional small dedicated water  pump to help shed all the heat from the turbos, except it takes much longer with all that heat trapped under the hood, so wenting it out reduces the heat stress on many components other than just the turbo charger.

The egine’s coolant also should be refreshed in every five years in most cases as a preventative maintenance, as there are no fluids exist which last forever.  Please make sure the type and composition of the coolant is proprietary for most manufacturers so it’s absolutely essential to use the proper type of coolant to prevent cooling system degradation and corrosion.

Please inquire within if you are unsure which fluid belongs to which make and model. Sometimes there are clearly visible differentiation like BMW uses a blue color so does Mercedes Benz.  Porsche uses a pink coolant older Mercedes uses a yellow coolant, each has their unique chemical composition and should not be mixed in any event.

We recommend professional assistance if unsure about the proper fluid for the make and model of your vehicle.

If you have any question, please don’t hesitate to call us. Our phone number is: 905.795.0419 We wish you all the best.

Preventative Maintenance and Your Car

We often get the question how can I make my car last longer?

Does not matter what type of car you drive, it can be a domestic or an import, either way the answer is maintenance above all. Proper timely maintenance, tune up and engine service, is absolutely essential for any car, regardless of make or model. It’s in the name of the procedure called preventative maintenance as simple is that.

A little common sense goes a long way,  we have some really long distance driven cars  to prove it.

We recommend oil changes at ten thousand kilometres, use high quality long-life synthetic motor oil.  Than  coolant flush and fill at least every five years, brake fluid service at every second year, transmission and differential, transfer case fluids at every hundred thousand kilometres, the rest should be a breeze.

Most manufacturers like BMW, Mercedes Benz and Porsche has their own spark plug and filter replacement schedule. They are the minimum standards to follow at least.

Artificial intelligence built into cars

The new technologies are just cropping up suddenly almost every day. Where are we heading to with all this new technology and advanced cars? Appears to be the autonomous driving is just around the corner and we will be able to just play on our cell phones and or watch entertainment on the go.

Artificial intelligence (AI) is so cool and we will be taken over by machines so the media want you to believe, I say not so fast just yet . There seams to be a misunderstanding between reality and facts.  Yes we have some intelligence built into modern cars like lane detection and active cruise control, side detection as well.

Yes, there are some cars capable to take some control from human drivers, but make no mistake the object of proper recognition of dangerous situations and correct prevention in timely action is not here yet.

Driving is a very complicated task, the human brain is not just capable to assess or recognize dangerous driving related changes or obstacles, but it can reason or avoid dangerous situations in milliseconds. As of today no any current automobile’s artificial intelligence able to this, regardless of the multiple radars and lasers mounted on it.

We will have human drivers for decades to come. There has to be much more research and development to be done before this technologies can be handed full control of your vehicle with their occupants safely.

Winter Driving

We are going to deal with a seasonal weather change soon, which will require some serious adjustment in driving dynamics and economics.

Yes, you guessed it right, we are talking about winter driving and cold frozen roads occasionally snow or ice covered by sudden weather conditions. We highly recommend to properly prepare your BMW, Mercedes and Porsche for this season, which should include of checking the tires and replacing them with appropriate winter tires.

Furthermore you should get your import automobile’s cooling system check out for any leaks or defective worn hoses. It’s extremely inconvenient to break down in the middle of a snow storm or in any winter conditions. It is always inconvenient to break down needless to say in winter, perhaps it is possibly the worst for obvious reasons.

We also recommend to check your car’s service records for the age of your vehicles coolant, suffice to say it should be replaced in or after five years. Chemical degradation is inevitable in a closed high temperature mobile system with multiple dissimilar metals and components.

We recommend a cooling system service which is rather inexpensive in every five years to keep your heating and cooling system in top shape.

The vehicles braking system should be also inspected closely (it’s a perfect time when you switch to winter tires) most folks don’t realize your traction or stability control works by applying your brakes at an accelerated rate to help you keep your vehicle under control. We naturally recommend a complete per-seasonal inspection and last but not least checking and – or replacing your car’s wiper blades, if needed for a clean clear view.

We wish you safe and comfortable motoring in the coming winter season.

All the best from Techmax Auto.
