Engine oil Castrol or Shell

Jeez I feel like an outcast. I run Castrol 20-50 lol but the car loves it

I might switch to liquimoly like a lot of ppl do but I’ve always stuck with the Castrol edge 5w-40, changing around 5k

I been using castrol 5w40 since I got the car new at 82 miles no issues. Sent my oil samples to blackstone for analysis and oil is really good even at 10k.

Worry less about the now old 502.00 spec than the actual oil itself. It's API SN/CF and has MB-Approval 226.5/ 229.31/ 229.51. Even though 505.00 and 505.01 are diesel engine specs, it should be fine in your older car. One of my go-to oils is Shell Rotella T6, which is specifically for diesels, but it's a great oil.

That's what the dealer and I use. Castrol 5W40

Its honestly all good, I ran Rotella T4 for a while, still good.

A few years ago Castrol decided to dye all their Magnatec oils green... it was pretty dark green as well.

I used to use German Castrol 0w20 in my Volvo and it was green too.

I use 10w40 full synthetic oil, and only the best quality stuff. Valvoline, Castrol, Pennsoil, Mobil1, Idemitsu end the like. Before my rebuild, I was using Idemitsu Rotary blend but switched to Castrol GTX. The GTX semi synthetic blend had a slightly lower oil temp and lasted longer per oil change than the Idemitsu, indicating that it was lubricating better.

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.
