Engine oil Castrol or OEM Volkswagen

After using German Castrol on my mkv back in the day my mpgs went up significantly.

A few years back I picked up an S65 engined M3 (E90) after work on a Friday. I hit the 155mph limiter that night, Sunday morning it was doing track duty. In 3 years and 50,000 miles it had 3 oil changes and the 1qt of Castrol Edge TWS I kept in the trunk for top-ups still had some oil in it!

My car uses about 0.5 qts of oil every 5000 miles. I think castrol 5W 40 is the best oil for this car.

I did notice the German Castrol had a smoothing effect on the big 5-cyl.

For my 24v I use: Castrol Edge Professional OE 5w40

I've been using these docs for a while now, and am incredibly grateful for you sharing them. With that said, I just noticed something that's news to me. Both the \"Revised Oil Capacity Job Aid\" and the 2012 vs 2013 fluid capacity charts show a 1 qt decrease in engine oil capacity between 2012 and 2013 MY. I've always heard there were insignificant, minor changes between the model years. I've been putting 5ish into my 2012 and it's always been full according to the dipstick.

Best oil IMO is Castrol 10w40 high mileage part synthetic, usually good specials at local auto parts stores and Walmart.

I'm in LA and I use castrol oe professional 5w-40 on my rebuilt 16v. The best oil I've used so far in my mk2 and I've tried a lot (Rotella t6 5w-40 Mobil 1 15w-50 and Total Elf 5w-40) all synthetics. Try it out. You won't be disappointed.

I use 5w-40 Castrol Syntech oil in my 2010 3.6 CC. I believe that if you are going to keep the car for a long time( over 100k miles) then I would use the thicker oil for better lubrication and wear protection. Owners in warmer areas like myself should use the 5w-40 due to the higher summer temperatures which will break-down the 5w-30 oil faster than the 5w-40 oil especially after a 10k oil change period.

I put mine in around 20k. The first change I did - it had 2 small metal shavings. I got very nervous. Ever since then there has been the powder you have in the pic above. Sometimes more sometimes less. The 2 times I have used Castrol I found more than other times (This could mean it protects less or that it carries the particles better than other oils). I will only become worried when I start seeing shavings. To me it's only an additional monitoring system. Like in a tranny - powder is ok, but shavings mean save up some cash. oh and my car is now at 125k.
