Engine oil Castrol or OEM FORD

I have been told the same by Blackstone on my cars, though I still do it once a year given the cost is <$75. However, I do follow their advice on intervals, after once being a 5,000 mile interval guy. On all three of our cars, using Castrol Edge 5W-20, I've repeatedly gotten analysis that tells me that, at 7,500-10,000 miles, the oil is still performing as intended.

I've had good luck with Castrol for several years in two WRXs.

If your interval is 30,000km / 20k mi (2Y) then you should use the higher spec VW 503 / 504 (left page) if you have the 15,000km / 10k mi (1Y) interval then you can use the lower grade VW 501 / 502 oil on the right page.

I always use Castrol, good quality oil won't hurt the engine and is just slightly more expensive than off-brands.

any oil that meets the LL-01 standard will do, buy whatever is on sale. Castrol Edge Euro 5w30 is fine, Mobil 1 euro synthetic, whatever.

As the owner of a 1995 Ford F-250 Powerstroke, the saying goes, "if it leaks oil, it has oil". -Ford 3:16

My conclusion was to use the best Castrol in the gold bottle. Of course, YOU must use the specification of weight recommended by the owners manual for the temperature range you expect to be operating in.

The gallon of Castrol is the same whether you buy it at CT or Napa.

I use the Castrol 10w50 that the dealer gives me for my 18 RS. I have clutch slip issues and it seems to keep it mostly under control vs Motul 7100 or 300V

I will never use castrol again, stupid dark bottle is annoying and makes it hard to tell how much is left
