You car’s air condition system should be inspected every year. Even if you don’t suspect any problems, it’s a good idea to have that AC inspected, serviced and cleaned once a year, to make sure it operates efficiency and ready to cool your car in any hot summer day.
We, here at Techmax have three basic solution for your car air condition.
The first is for working but smelly AC. LIQUI MOLY Climate Fresh will fix this problem. The spray is a deodorant for cars that every driver can use themselves. The self-emptying can is set in the foot-well and the air conditioner switched on. The substances spread in the ventilation and free the air conditioner from unpleasant odors.
If this can’t eliminate the odor, than we need to clean the AC. We use LIQUI MOLY A/C System Cleaner.
This is also applied as a spray as well, except it not just to eliminate the odor, its clean the system also. This AC cleaner, ensures that not only the lines, but also the evaporator of the air conditioner is cleaned.
The third is the best method.
It is diagnose – clean – repair and re – charge.
The cleaning will be done with LIQUI MOLY professional AC cleaner.
This cleaner made from two components, we mixed them just before use. The cleaning liquid is applied to the evaporator with a special tool and reliably eliminates bacteria and mold.
The above three methods – the simple Climate Fresh for eliminating unpleasant odors, the A/C System Cleaner spray can for quick cleaning and the 2K A/C System Cleaner for thorough cleaning – cover the entire spectrum.
Visit us and your AC’s hot air and bad odors from ventilation will become a thing of the past. Call us for further details. Telephone: 905.795.0419.
Why do I need to top up my oil between oil changes?
It’s normal for cars to burn a little oil as they age. The most common reason why an engine loses oil internally, the oil is slipping past the piston rings. All cars have it happen to some extent, especially when revving the engine at high RPMs.
This is usually older cars’ problem, where the piston rings are a little worn. It is not a big problem unless it is excessive. But it can also happen on some newer cars.
There are many different reasons for more oil being consumed by modern engines, here goes the list.
Today’s modern combustion engine is a super slim, lightweight marvel of engineering. The internal moving parts has been reduced “optimized” for the lightest possible to reduce fuel consumption, including the pistons’ size. The rings has been also slimmed down with low ring tension. This minimize friction, which result in more oil to be able to escape and get burned in the internal combustion engine.
Worth to note; the stoichiometric ratio, relatively speaking is fixed, which is 14.7 kg of air with 1kg of fuel provides the cleanest most effective combustion. This particular ratio cannot be changed too far in either direction, or the combustion becomes inefficient in the long term. This is why the engineers had to look for different solutions. This resulted in lighter more efficient internal components, including lighter weight motor oils.
Therefore lighter weight motor oils are chosen to reduce internal friction with minimized pumping losses and being lighter also easier to burn.
Definition of is stoichiometric ratio;
Combustion engines’ stoichiometric ratio (AFR) is the mass ratio of air to fuel present in a combustion process.
We could go further into the additional technical details, like running the crankcase ventilation under high vacuum to minimize reduce the pumping losses.
As you can see, there are multiple reasons for the oil consumption of a modern high tech internal combustion engine.
Last but not least the government legislated corporate fuel economy worldwide. This also having a serious effect on the design and manufacturing of today’s efficient internal combustion engines.

Spring service is the time to get ready, gear up for more travel and longer drives to your favorite destination wherever that may take you on your journey.
Most spring service consists of changing of your tires from winter to summer and while we are at it inspect your brakes and the suspension as well. Suffice to say we do the general check up at every oil change or required service intervals to keep your car and your family safe on the road. Frequently Asked Questions About Motor Oils
This in fact one of the most important benefit of having your car cared for by someone whom has a relationship build with over time which in turn beneficial to both parties, as it should be in any business.
We will do inspect common trouble areas as every make and model has their own pattern issues which could be only achieved by a specialist whom concentrates on a few manufacturer solely.

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.
Please also pay special attention to specific ACEA designation by each respective manufacturer of all the European automobiles.
We will be happy to assist you if you have any questions, give us a call to 905.795.0419

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.

BMW Alpine D3 Diesel Bi Turbo
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.

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.
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.
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.

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.
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.
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.
