how much do u want to spend?

Now dont get me wrong I have no problem with conventional oil.. if I used it I would use GTX thats my preference.. HOWEVER IMO the synthetic oil is a better oil and its not that much more in my eyes.

I guess I'm speaking from an S4 N/A perspective. I spent a total of about $1000 to have my engine rebuilt so it seems foolish to spend that much on oil. However, if I had an engine with new housings/plates/etc., I might justify the synthetic.

Well honestly there is people who will drop 10G into an engine and still wont use synthetics and thats ok again oil will ALWAYS be about choice..

I use it because I think ANY engine will benifit from it thus why I added it to my 220K bmw, my wifes 150K jeep and I will use it from the begining in my turbo rotary engien when I am done..

hell I used it in my n/a engine.. at 70K it was well worth it. IMO

I'm a conventional man myself. For me, putting out 400whp my oil gets dilluted with gas FAR FAR before the oil ever reaches its useable life span in mileage. I change it roughly every 2000kms.

10-30 at the start of the season, 20w50 in the peak of summer, 10w30 in the fall.

IMO, once you get much above stock power and are injecting a little more then stock fuel, your oil will be contaminated very fast. Whether you do $45-50 dollar synthetic chnages, or $15 dino changes the oil gets gassy either way and needs to be changed....so I opt for the cheaper of the two options.

EDIT: its also just carquest brand oil since I deal alot with them. I also use their oil filters which are carquest badged WIX filters.

In a rotary engine there is a high amount of surface are that slides (ie, apex, side, corner seals, oil seal steels). Many, many professional engine builders and hobbyists have seen what can happen as a result of new auto oils not having the same additives as they had just a few years ago. The catch to all this is that "diesel" oils still have the zinc in their package. I've been running Rotella for years without issue. Both the standard and synthetic formulas. If you still have the OMP connected then you'll want to stick with the non-synthetic.

From Chris Ludwig, that's why I started using it.
