IMPORTANT QUESTION

[AZOOZ_95]

Thanks a lot guys , with things u guys have told me i went to the dealership, and told them that they have to provide the recommended oil for the car. Turns out they dont have the recommended oil is because they dont sell much of the gt86 here . So, they said they're going to contact there oil supplier, and see if they make it. If that doesn't work out I told what if i got the oil and u guys put it in, he agreed and said that it wont void my warranty.

The oil companies add polymers that actually thicken up the oil as its gets hotter(to a certain point), which gets the oil to the last number. So a 0W20 oil will flow like a 0 weight oil at startup, and a thicker 20 weight oil when running at 100 C.

Common misconception. The oil gets thinner as it gets hotter.

The VI additives stop conventional oil from getting too thin as it heats up. Synthetic oil really doesn't rely on VI to maintain correct viscosity, the oil is assembled or refined to ensure the heavy waxy elements that cause oil to thicken when cold just aren't there. The lower W number means the oil has equivalent viscosity to a straight weight oil of that number when cold, not when hot. A zeroW (0W 20, for example) means there is no straight weight oil with that viscosity when cold.

It really matters what that W number is because that's the oil protecting your engine while it was up. VI additives were invented to protect your engine when cold, so that much lower viscosity conventional oil could be used. Conventional oil is not like synthetic. It matters which you use in some engines, such as our BRZ.

OP is not in the US/Canada. In "small volume" countries, this can be normal.

I assume factory warranty is the same all over the world..? Could be wrong

I keep seeing references to the first number representing viscosity when "cold". It is actually the apparent viscosity results during the Cold Cranking Simulator test at -35C for 0W oil and -30C for 5W oil which is not very relevant to the OP.

http://www.pqiamerica.com/coldcrank.htm

Unfortuntately, it's difficult to tell what the oil's actual viscosity is at a given temp like 0C or 20C. A viscosity graph does give you sort of a ball park of the actual viscosity at a given temp (although it may not be 100% accurate either). http://www.widman.biz/English/Calculators/Graph.html

Plugging in the Mobil1 N. America viscosity numbers at 40C and 100C for the 0W-20 and 0W-40, you can see that the viscosity of M1 0W-20 is 44.8 cSt's and 0W-40 is 75 cSt's at 40C/86F. As a comparison, M1 5W-20 is 49.8 and M1 5W-30 is 61.7 at the same temp. This probably represents a "cold start" for the OP.

Most 0W-x oils, regardless if conventional or "synthetic" do contain Viscosity Index Improvers. Ester based 5W oils like Red Line or Motul 300V usually contain less or no VII's, but most companies (even Red Line) need to add them to the 0W-x oils to meet the CCS spec. You can contact Red Line for details.

AZOOZ, it's good that your dealer is trying to get the right oil for you.

Warranty is never the same between countries, even from the factory.

Case in point:

US: 3 years 36000 miles
Taiwan: 3 years 100000 KM (62500 miles)

Europe: 5 Years.

Azooz! I live in Lebanon and I was facing the same problem, they were using 5W40 when the recommended oil is 0W20. I've lived in Saudi before and I know how hot it can get.

I started the 86 Club for Lebanon so I've been in constant communication with the dealership here and I've raised the Oil issue with the Managing Director and the Head of After-Sales Service.

They contacted Toyota Japan requesting additional information regarding the whole oil thing. Toyota Japan replied that depending on climate / humidity, local fuel quality, environmental conditions (such as dust or whatnot), etc., the Toyota engineers in Japan recommend the heavier oil for the GT86 for Lebanon.

I believe it might be a similar situation in Saudi also, just wanted to let you know especially with temperatures getting as high as 60 celsius on some days.

Actually, the U.S. is 3 years/36k miles for the bumper to bumper warranty and 5 years/60k miles for the powertrain warranty.

This actually turned into a pretty interesting thread. Subbed, and good job guys.

Good luck Azooz!

I know, I'm just stating the warranty in other countries are drastically different.

Most people would only make use of the 3 year warranty under normal circumstances.

Dont you guys have a Subaru dealership in Lebanon? They will MOST definitely have 0w20

EDIT: But I agree with that recommendation for heavier oil

We do have a Subaru dealership in Lebanon. Actually, we merged the 86 Club into the 86 BRZ Club and we have the son of the owner of the Subaru dealership with us in the group.

I can check with him if they have the oil or ask what oil the BRZs are using.
