Engine oil Castrol or MOTUL

On my MKV GTI when I switched to a thinner Motul from a thicker Pentosin I noticed a good bump in power.

Have my best experience with Castrol 0W30 (European $8.99/qt) Minimal lifter noise and run it 5k between changes. Also, use OEM oil filters.

Good quality synth 5w40 alllll dayyy eryyy dayyy. Flip open your owner's manual, 5w40 is the recommended oil. 30 weight thins out too much during extended drive periods or in high temp areas. FWIW the previous owner of my Golf sold it because it was an "oil burner" he was using gas station brand dino 5w30 :screwy: I switched to Motul and then Gulf 5w40, and drove it for 55k+ kms, had to add about 1L between my 10K OCIs.

i tryed the castrol edge sport 10w-60 and its working great (very smooth & quiet,etc... any way better than the 4w-40)

always ran castrol gtx diesel 15w-40 in my old 1.5 no real reason but when i bought the car it came with a case in the trunk so i just kept at it. motor never had a problem, and it ended up getting swapped into my buddy's rabbit and boosted.

Edge 5w-30 did great for me. It's a great product, turning in the best 1.8t UOA I ever saw. There are PLENTY of great products dirt cheap on our shelves. I personally feel SynPower is most worth of my money, on a full price basis. Otherwise, I'll buy any other NAME BRAND synth when its' $4 or so. I actually nabbed a bunch of Quaker State 5w-40 from BigLots for $4ea. QS is a sleeper oil, esp at the right price. High moly too, great for break-in.

I used Edge in my APR 2.0TSI over winter, did a lab report and wear was minimal, actually the same as a Motul 5w-40 sample from the same mileage.

Well, today is the day. My TT get's its first oil change. Motul X-Clean is going in!

GC 0W30 is PAO based oil. PAO and Ester based oils are much more stable and clean engines much better. People who need 502.00 approved oil simplly LOVE that thing!

I am sticking with 0W30. Plus, it is better for cold start, which is one of the most important things!
