Owner reviews for engine oil

Currently using it on the 16V. So far it has quieted down the top end valve chatter. Also it has stopped the Oil Evaporation issue I had.

I ran it as a year round oil in my s2000 and a winter oil in my evo. Great stuff. Cheap too.

It's a great oil, use it

I use Rotella T6 on my 2.0T. it's fine.

I use Rotella 15W40 in my BMW. It is good stuff.

I prefer Castrol 20w50 in my 1976 CB550, at least in the summer. Non-Synthetic

Thanks for updating, it is nice to see a progression like that. A full history through 25k miles and things look pretty good on the Rotella T6.

I'm using Castrol Syntec Euro formula which is a 0-30 oil. I've been doing oil analysis with every oil change since I got the car. This change was a short interval with just 1400 miles on the oil between changes. Right in the middle was a track day where I did about 130 miles on track, six 20 minute sessions. I think I was seeing peak oil temps in the 240s with very quick recovery back down below 220 during cooldown.

I run Mobil 1 5w30 and still change it every 5k. I could probably bump it up to 7500 or 10k but don't because I do it myself, and it isn't a huge cost or inconvenience to do it early.

I run the extended performance Mobil 1 in my Toyotas at 15k mile intervals, with an oil filter change every 5k miles.
