Engine oil VALVOLINE or Shell

Valvoline Synpower 5W40 I've been running this (VW 502.00 approved) in our '07 Audi 2.0TSI for over 100K mlies, 10K oil changes, and no issues.

Valvoline SynPower Full Synthetic 5W-40, VW502 approved. I use it in our '07 A4 (over 100K miles) and plan to use it in our '16 GSW.

5W-30 Valvoline SynPower (full synthetic) and Mahle filter since I picked this car up at 89k in '11. Just cleared 175k last week.

You need to run the 507.00 spec oil. I have been running Shell Rotella T6 Heavy Duty Diesel 5W-40 oil. They other one that I want to start using and is more widely recommended is Liqui Moly 4200 Top Tec 5W-30. The reason why I mention this is because the 507.00 spec oils has better lubrication then the other 501 and 506 spec oils. If the wrong spec oil is used it has a tendency to produce premature Cam shaft lobe wear requiring the replacement of the cam shafts.

personally, I'd use Rotella T6. It's a full synthetic oil marketed for diesel engines or "heavy duty" but it's a low saps 5W-40 oil that is perfectly fine to use in a gasoline application.

I have always used 15w-50 on VR6's and 5w-40 on 1.8t's and 10w-60 on the track cars. Try out Rotella T6 5w-40. I ran Motul 5w-40 on my 911 and it made tons of extra noise, went to Rotella T6 under advice from my tuner and it quieted it right down. Been using it on my Saab as well which has a noisy chain setup as well and it worked wonders.

I think what helped as much is the valvoline oil. Valvoline really agrees with my motor. Not sure why I have trouble with some of the other blends, but it's really quiet with the ashland add-pack.

I've been hearing lots of good stuff about Rotella t-6 i just changed mine to that the first time this month for the winter

So this morning I went n got some Rotella T6 5w40. filled her up and drove it pretty far. The light didnt come back on. I guess all I needed was an oil change? Sounds a lot quieter in idle too, no ticking besides the fuel injectors.

I go back and forth between white jug rotella in the summer and t6 in the winter. It's cheap, and I've never had any issues.
