Reviews of Castrol engine oil

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!

have used Castrol 5w-40 as VW calls for and change at 5000 mile intervals. Now at 129K, it still uses one or two quarts between changes and performs as well or better than new.

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

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've been running Castrol 5w40 in my car and have had no problems.
