If it's 4.2, that would make it significantly better than the M1 TDT I'm currently using. A lot of people go ga-ga over T6, but the rest of the specs don't seem to make it much better than TDT. RL 5w40 really impresses me, but I need to get over my phobia of having to make a 120-mile round trip to buy it.
Since my truck is a 2001, I'm trying to avoid putting CJ4-only oils in it. I look for the CI4+ notation in the API service symbol. M1 TDT has that, and at $21/gallon, it's a good deal. Other factors that are pushing me to avoid CJ4 oils are the High-performance tune that I am running, and my occasional use of WMO in the fuel, up to 6%. Both of these push the requirements for high TBN.
Where are you finding 3 or 4 year old oil at? (CI-4+ TDT)
I'm not. I'm looking at the API Donut on the back of the bottle. M1 TDT has the CI4+ notation in the lower portion of the Donut. RT6 doesn't. I just checked a bottle when I was at the parts store on saturday. For me, it makes it more likely that TDT meets some requirements that RT6 may not.
