Engine oil Castrol or VALVOLINE

I use Castrol EDGE Supercar 5w50. Oil change 7000km ????. no problems! Mileage 150 000km . Car from 2014!!

300.000km - oil: Castrol Edge 5W-30 and a new vortex breather - without oil consumption

315.000km - oil: fuchs titan 5W-30 and the old vortex breather - around 1L oil consumption

330.000km - oil: mannol 5W-30 and the old vortex breather - around 1L oil consumption

345.000km - oil: eneos 5W-30 and a filter type breather - without oil consumption

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.

Valvoline Restore & Protect. Its no joke.

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.

I use Valvoline Synpower

I’ve gone down an oil research rabbit hole many a time. There’s been some extensive studies done and besides liqui moly, studies have shown that Valvoline extended protection has some of the best wear-prevention additives and performed among the best in lab samples pulled from used oil.

I've used both, M1 was quiter and yes it did burn a quater quart more in the same period.
