liqui moly synthoil high tech 10w60 outside TEMP100F:evil: and my car
forced induction:burnrubber:, after warmup in the first 10min driving there is some
drag feeling then it gose away . Is this oil good for me it will not harm my engine ?:iono: any recommendation ill be much appreciate it.

thanks...:thumbup:

I feel sorry for your engine

what do you mean cmon don't freak me out!!! :bow:

Do you have a built engine with bearing clearances that need a 60 grade? If not, and you have stock internals, an ACEA A3 rated 0W-30 like Liqui Moly Synthoil Longtime is all you need. You will definitely be freaking out when you have cavitation from running an oil that is too thick. :bonk:

Many people think that using a 10w-60 is necessary in almost any modified car, especially ones with turbos, and that is a very old-fashioned approach to lubricating a performance car. ... The thicker viscosity oils lead to a slower oil flow rate, which can lead to several problems. There can be localised high oil pressures in the engine, causing increased wear at certain points as the oilways are not designed to cope with the thicker oil. One of the main functions of the oil is to carry heat away from the engine and that is then cooled by the air flow over the sump – with the thicker oil the flow rate is slower, meaning less heat is taken away and higher oil temperatures occur (that can also lead to people thinking they need thicker oils). In a worst case scenario with thick oils (when not required) is that you will experience air entrainment and cavitation inside the bearings at high RPM. Not clever stuff!

what about the outside temp extremely hot and the mechanic been using this kind of oil for GTR R35 customers so u mean this kinda 10w-60 is way too thick for extremely hot weather still thick ?100-114F here

Parts of the U.S. have temps like that every day and the spec is still 0W-20. Thinner oil actually cools better. Yes, a 50 grade or 60 grade is way too thick. Even a 40 grade is too thick unless you are highly modified.

Remember, thin as possible and only as thick as necessary. If you have an oil temp and oil pressure gauge, you will know if the thinner oil is working for you or not. Do not assume that just because it's freaking hot there that you will need a 60 grade. :)

Read the above article.

Crawford Performance runs 0W-40 in their highly modified, built 500 hp BRZ.

Engine at operating temperature is around 100c and there is no active cooling solution, hence there is little dependence between oil temps and ambient temperatures. It definitely will increase slightly but nothing to justify going to a oil weight that trucks use. If you're concerned about protection due to your ambient temperature go for a 30 wt oil or an oil cooler. 60wt is ridiculous

isee... thanks alot

The most important measure for oil weights is the corresponding pressure it provides when pumped inside a crankcase. You should take necessary steps to maintain this type of pressure via changing weights, oil cooler, dry sump, etc. as the need arises.

Just by going with a heavier weight due to ambient temp isn't going to solve any issues.

how about goin 5w-40 is It still thick or sounds good?
and how about underhood I cant pull it up without tissues extremely hot but in dashbored the needle shows im still on normal engine tempture

our dealer been using for FRS customers 5w-40 full synthetic for (STOCK FRS) what do you think?

Still too thick unless your manual specifically allows 5W-40. In all likelihood, the thickest that you'll see in a any GT86/FRS/BRZ owner's manual or factory service manual is 5W-30. Why can they import an entire car and can't import a few pallets of oil?

Shieettt, they could go down the street and grab some! Oil flows like water in the Middle East right?

Yeah, but where do they refine it into Passenger Car Motor Oil? :)

Djen - I just read at bobistheoilguy.com that GM dealers in Kuwait get Mobil1 5W-30. I do recall some other Middle Eastern posters here having a similar problem as you and dealers not honoring the warranty if you do not run the oil that they recommend.
