Which is better? Synthetic or conventional motor oil?

What makes a motor oil Synthetic motor oil? The word “synthetic” has a pretty loose definition, a lot of manufacturer prefer the word synthetic to only apply to oils chemically formulated without the use of petroleum as a base oil.

However it is not that simple. At first lets talk about petroleum based motor oils. Petroleum based or Conventional motor oil is a lubricant that is produced directly from crude oil.

Petroleum base motor oils are very “sensitive” to temperature changes. This means at extremely low temperatures, for example at winter  time, here in Canada it may be thick, and at high temperatures, it’s fairly thin. To change the oil properties, oil companies mix additives, chemicals into the petroleum base.

Those chemicals effects the oil  viscosity,  improve it at high and low  temperature too.  When a 5W-30 conventional motor oil is brand new, it  can acts exactly like a 5W-30 synthetic motor oil.

The problem is comes with time, from the use, the chemical additives in the conventional oil begin to break-down and or vaporize. This means, the oil starts to get thick when cold and start to get thin when hot.

Synthetic oils work quite differently. From the start, the chemical structure is designed to match a specific multi-grade oil, plus certain additives like rust inhibitors or dispersants will be added to further improve the usefulness of the oil.

The end result is that over time the synthetic oil does not degrade as conventional oils do. From a viscosity standpoint, an old  synthetic oil act pretty similar to a new synthetic oil, however it might get slightly thicker as a result of contaminants.

Some people states it, from a viscosity standpoint alone, a conventional motor oil could match the protection of a synthetic motor oil simply by changing conventional oil  more often, and it is  true. However synthetic motor oils not just lubricate only, they come with superior quality additives, leading to a cleaner, smoother running engine as well.

Which one is right for your car? Which one is better? Synthetic or conventional motor oil?

Before any misunderstanding, probably hard to buy a bad lubricant these days. some of them good  and some others are better. Even the most basic conventional oils available on the market are far better than ones offered 10 years ago.

We believe, it’s ok to use a quality petroleum-based oil in an average car, but if you drive a luxury or a high performance vehicles, we recommend to follow the owner manual’s recommendations, which is synthetic oil.

For sure, the synthetic oil cost more, but the benefits of synthetic justify the expense, with longer oil changes intervals, reduced oil deposit formation, slightly better fuel economy and longer engine life.

Is your car AC blowing smelly hot air?

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.

AC cleaner

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.

My car’s engine burns oil

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.

Manufacturer Endorsed Tires

The season for tire change is fast approaching as spring comes closing up.  The winter tires will need to be removed and summer or alternatively all season tires needs to be installed.

This may mean for some of us new tires needs to be purchased and fitted for the season.

BMW run fllat tire

Run Flat Tire

Choosing the right tire for the car is one of the most important purchase you will ever make. There is a new phenomenon which is manufacturer endorsed tires, this is a relatively new thing and mostly European manufacturers started doing it.

The question remains, could you or should you use manufacturer endorsed tires only on your BMW or Mercedes? The short answer is no, the manufacturer endorsed tires are a safe bet if you want to follow their guide lines but logic says it is physically impossible to test every single tire on every model on every make, so for the very reason I recommend to consult a licensed experienced technician with decades of tire know how to select the best tire for your fine automobile.

You should never base your tire purchase on price or impulse only.  Be cautious with large chains whom only have a wasted interest to move their stock tires and operate at volume sales at very thin margins.

The rule of thumb as always, you get what you pay for.  Same goes for advice, online information also should be treated with caution since most people rating tires are by no means experts on the field of tire evaluation.

We hope this will help to have a more informed choice.  Please visit  or call us for further details. Telephone: 905.795.0419.

We wish you all the best at Techmax Auto.

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.

Fuchs Synthetic Motor Oil Fuchs Synthetic Motor Oil for Your Fine BMW – Mercedes – Porsche

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.

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.
