Engine oil Castrol or VALVOLINE

Better to use cheap oil and change often than to buy expensive oil and run it out to 10k+ miles. Personally I typically use Castrol products and change my gasoline engines at 3k and Diesel engines at 5k miles.

As a Shop owner that Services a ton of Euro Cars we pretty much use all the Valvoline Euro Spec'ed Oil. They meet all the OEM requirements as we've also sent it in for testing. I have a 2014 CC APR Stage 3+ and thats what I run, Valvoline 5W40 Euro. No Issues.

I use the castrol gtx high mile full synthetic 10w-40 and a sohn adapter with ideimitsu. I’m sure non of the name brands will hurt As long as you change it frequently.

I change every 10,000 km - 7000 mi.

Castrol or Mobil full synthetic.

To me that is much better than running any brand of oil longer.

I’m a Castrol 0W40 guy myself.

It doesn't seem like I burn any oil in my Rabbit. 0w-20 seems too light to me, also, I'm running Castrol Edge 10w-40.

Valvoline vr1 20w50 I'm convinced they basically make it for rotary's to begin with.

I run Castrol GTX 10w40 in my FD. Premix TCW2 2stroke oil .5oz/gal.

Engine seems happy as can be.

I use mobil1 or castrol full synth 0W-20 for prius engines below 200k and 0W-30 for those above it. More than 30k mi now so far so good. I like the castrol better bec my engines sounds much quieter vs m1.

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.
