Default What's the final word on oil to use for 2.7T engine?

I did searches, and found many opinions.

After all of what has been said and driven, over thousands and thousands of miles by you guys, what is the final word?

Stick to synth 5w30 (stock recommendation) ?

Or 10w40?

FYI I do not autoX or track the car. I dont even put 7k-8k on it per year either. Live in New England, and I do lots of city driving.

To note, my mechanic that did my timing belt suggested to me if I wanted to, to put that 0w50 oil ( i think that's the weight) which is exactly the brand used for M3's and M5's. Thoughts?

Thanks!

Default In a non-turbo engine, does using a good synthetic safely allow for longer change intervals?

I remember the marketing hype from when synthetics were first introduced. I just bought a new Honda and am contemplating using synthetics. If I have to change it every 3-5k miles anyway,however, I'll stick with the dino.

Probably, but I still run Dino oil and change at 4k.

Default I think you could go 10K between intervals if it has the...

ACEA long life labels. Audis have pretty large oil capacities. I think minimally you can go 5-7K.

If you lease, 10K it is (Audi's engineers seem to think it is ok).....

I see no reason the Honduh couldn't run 6500-7000 with a decent synth.

Default Agree

the biggist variable is you driving style and environment.

Given normal driving you should be fine with 10k intervals.

Keep an eye on the color of the oil. It should look amber and not dark.
