Engine oil VALVOLINE or Shell

something you might consider is switching to Shell Rotella T6 5w-40.

you can find many testimonies to the benefits of using T6.

I’ve used a few but the best for me is mopar oil filter and Valvoline full synthetic.

My 1.8t is currently filled with Rotella T6 and I swear its eating less oil now (or maybe I'm getting better with my heavy foot)

I’ve been using Valvoline full synthetic with a KN filter. Never had an issue

Valvoline full synthetic with max life tech is my current favorite but I think I might be able to unseat him soon.

I always buy engine oil from Lotus (Tesco). Shell Helix especially on sale.

I personally use 5w50 valvoline fully synthetic racing oil for my r56 and change every 5000 km which is like around 3k miles and it's running good

For the money the best zinc content is valvoline vr1 CONVENTIONAL (not synthetic). It comes in a few flavors.

The same oil goes into all GDI engines at my dealer, which is Shell Helix Ultra SP 0W-20. This is a super expensive, latest spec oil. Oil changes with this oil are done at 9320 miles if turbocharged and 18 640 miles if naturally aspirated.

I use Valvoline 0W-20 full synthetic and an OEM filter.
