Hi! I am looking for a blend to use in a 6.2 I ran it about 400 miles on 50/50 WMO and D2 on a trip, but the transmission went out (nearly) and so I limped back home after topping the tank off with D2. The trans in finally fixed, and I just replaced the IP and inkectors. It was running really bad even before the WMO, though it seemed to run about the same on it as it did on D2 before ( I really couldn't say but it may have been slightly better even. FWIW, this was August in Tx with temps way in the triple digits.) I didn't realize how bad it was until now. Power is easily double. Right now, I have about 100 +- gal of oil and about 25 gal of WATF.About half of the oil and all the ATF has been filtered and run numerous passes through a centrifuge. The atf was also heated for a long time to hopefully remove any water. I saw several mentions of 85/15 and 80/20 WMO/RUG. Yesterday I tried such a mix- One gal RUG, about 3.5 gal WMO, and about .5 gal atf. Put it in another 6.2 that was nearly empty and fired it up. I haven't driven it yet. but it sounds about the same, but it smokes A LOT. I think the injectors are bad in this one also, as it doen't have the power of a 4 cylinder. I am going to try a similar batch in the other with the new pump and injectors. I don't mind using 50/50 if I have to, but obviously, a heavier blend would be nice, if I could get by without too much smoke, or risk of fouling my injectors in a short time. I am going to try to get more atf and less oil in the future, but that is easier said than done. Any advice on blending WMO, WATF, RUG and D2 will be greatly appreciated. Thanks ,
