Reviews of Castrol engine oil

I switched to Castrol Edge 5w40, and what a difference! It loves it. We didn’t lose any fuel mileage, just as Pepe. but much much smoother.

Car idles smoother with Castrol it seems.

I run 10w-40 castrol gtx been running it for the past 5 years I drive a 2011 wrx

ran Castrol 20w50 GTX in my 2.4 Naps Z D21 since new the mechanic who put on new head gasket w/215.000 due to a bad radiator said engine looked brand new inside

Used 5w40 castrol for most its life, but vw504 standard is good too. Using it now and the old man says it runs good.

One time I had the oil bug bite (keera) and I decided to get the best oil. Castrol (I don't remember the number) but it was 340 AED for a gallon. I poured it into the engine and it felt good. That weekend took it for a desert drive and during one of the breaks, the entire oil just leaked out of the main seal. The oil was so good that the engine didn't have the tolerances to hold it back.

My Mazda3 which I service myself now, Castrol edge 5w-30 and feels happier. Same engine too.

I always used blue "german" coolant in my e90 bmw oddly it also recommended Castrol oil. Specifically called for it in oil cap

i drive 85% freeway so i change the oil and oil filter every 7500 miles using Castrol Edge 0W-20 synthetic oil since 2017 no vehicle issue.

I put Castrol euro 5w-50 made for BMW and it's 6-7 liters and change it every 5000km I have a 2003 330ci and it still runs like new
