i have heard of a lot of oils claiming to be great for cars. however, i am torn on a few things. castrol syntec, in america here, is not pure synthetic. only in canada and europe, where it is, from what i hear the best out there. there is proof of this, as i have read it. i wil posta link to it when i find it. so, i guess what i am asking is, what are some opinions on the brand of oil to use for the rotory. for 4 years i have been using castrol. kendall, royal purple, and mobil non snythetic have all been reccomended to me, but i have chosen to stick with castrol. what do you guys think? dave

 

Do a search before asking. This topic has been covered lots of times before. You might start a flame war with this topic.

 

YEs deffinetly do a search. As said above this topic is covered about oncea week.
but after all you read, i still think it comes down to personal preferance.

I have run redline in my car for the last 25,000 miles and will never switch. period.

 

sorry about that guys! i will search. thanks. i don't want to start anythng, and i do apologize.

 

I run 4 quarts Castrol GTX 20w50, 1 quart MMO.
