Engine oil RED LINE or OEM Audi
I do not use auto oil. Motorcycles run hotter and I don’t trust car oil. I use Red Line. They sell a V-Twin kit that has engine oil primary oil and transmission oil, and fuel system cleaner. I buy one each spring.
Redline 5w30, the best
If you can use Redline 5w30, go right ahead. You will not have an issue. I call Redline the guarantee oil. I can pretty much guarantee that you will never have the dreaded lifter tick. It has been known to quieten a ticking engine too.
It's recommended by Nissan to use ester based oil. I use redline 5w-30. Pricey but I feel the difference and motor runs flawless imo
Using Redline 5w-50 on my E90 M3. it's supposed to have a similar viscosity at high temps as most 60wt oils. Comes up to operating temp faster and doesn't overheat.
I also switched to a 50 weight, Redline.
I was seeing moderate oil consumption and the heavier viscosity seems to have fixed that issue
The best oil to use is the RedLine full synthetic two-stroke Racing oil. Modern full synthetic two stroke oils are way better than older oils and work great.
Red Line products go in all my cars. AMSoil and Motul also quite good.
On my 1.8ts I usually change it when the motor blows up and has to be replaced. They used to last perpetually but builds have progressed to the "Yes it absolutely is going to grenade or window the block before 10k miles???? so really I only ever have to FILL oil 1 time???? I wish this was less true than it actually is. On the rest, (2.7tt and 4.2) 10k miles if you use good full synthetic oil and a nice filter
I've tested both those oils, and was not impressed with the results. Both oils still needed changing at 5k.
