Anyone use Rotella T diesel oil in their gasoline e30?

[e30trooper]

whats and good grade to start off when having a freshly rebuilt head? 5w40. M20 that is

[Stanley Rockafella]

awe man, that 5w40 is like water! ya gotta run like 15w or 20w at least!

[Bimmerman325i]

I run the Rotella T6 5w40 in my E36 M3 track car. Great stuff, good price, what's not to like?

[gtdragon980]

I've been running the 5w-40 synthetic in my e30 since I first got it. Great oil, and I also ride a SV650 which I run the 15w40 oil in. This shit is good!

[dinanm3atl]

Yup. Run the stuff in all my cars. In the Turbo M3 I do run the synthetic version.

[whterice]

I ran 15w40 in my previous m20. never ran into a problem and actually had less consumption then when I ran royal purple 15w40.

[stamar]

what about just any brand of diesel oil, like oreilly brand or napa brand?

is it only rotella or delo?

[jlevie]

VR1 is a slightly better choice than Rotella T, because of a bit more ZDDP. There is no advantage to using synthetic oil in an M20 engine since the oil change intervals need to remain at the factory specification. That interval needs to remain the same to prevent build up of combustion blowby condensates in the oil. I.E., you can't take advantage of the longer life of synthetic oil.

An even better oil in an M20 than either of those is Brad Penn 20w50. But it is much harder to find than VR1 or Rotella T. For more than you ever wanted to know about oil (or filters) wade through what is available at http://bobistheoilguy.com

I ran Rotella T (15w40, if I remember right..) in all of my past M20's. They all ran great. Don't know how much the oil had to do with it, but I wouldn't run anything else in an old single cam. It's got a solid reputation and the price is great.

i actually run the full synthetic rotella t in everything i own including my diesel f350 and my bimmers. even my lawn equipment and my kubota tractor. this oil is awesome and you can't beat the price. about 20.00/gal at walmart. i have been telling people for years how great it is. people are now starting to listen. i recommend you use it.

Higher levels of ZDDP can be found in Valvoline VR1 raceing oil.

Or the mobile 1 Racing oils.

As a general rule the CJ-4 oils for turbo diesels will be higher in ZDDP than gasser counterparts. These include Delvac 1300 and Delvac 1 from mobile, Rotella from shell, Delo 400 from Chevron is all good stuff, and will be great in a m20.

In my e30 I ran VR1 20-50 in My Duramax I run Delvac 1 (full syn). I used to know ZDDP numbers off the top of my head, and if IRRC the VR1 is 1450ppm and the Delvac1 is pushing 1700ppm. I may be mistaken but those are the numbers I am remembering.

http://www.joegibbsracingoil.com/ has oil with ~2400ppm but at $17-19/quart is well out of budget for most folks.

I think the great thing about rotella T more then anything is that its $12 per gallon.

Just bought some for my next oil change, from what I've read it works well.

I run the stuff, have been, and more than likely will be for quite some time.

Would running the stuff affect smog at all for ur car? All I know is that I wouldn't try it in California if it did.

ZDDP and Phosphorous are both considered low level cat contaminators. However, 1. It only applies if your consuming oil 2. Current warnings say it 'could' shorten the life of the cat rather then a certainty 3. In the 80's gasoline oil had high amounts of both before the EPA got at it and e30's back then ran just fine with cats.
