If synthetic 5w40 protects hot like it should

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.

They both meet CJ-4.

As far as what specs they meet, that can be found on their PDSs.

I know they meet CJ4, but that doesn't make them better for pre-2007 engines. I think CI4+ is the pinnacle for diesel motor oil specifications. CI4+ was introduced in response to engine problems resulting from the advent of cooled EGR systems in 2003, where they found that CI4 didn't sufficiently protect against corrosion and wear. So CI4+ has the most anti-wear additive, and higher TBN. The later stuff is formulated to protect after-treatment systems, which my truck does not have.

If you want a CI-4+ oil, Amsoil is one of the few out there.

TDT and D1 ESP aren't, T6 isn't, nor is any major xw40.

This might help explain what I'm saying better. TDT is not CI-4+ (nothing made since 2007). You've been running a CJ-4 oil.

 

[m37charlie]

Co-Op DMO SL 0W40 is CI4+, TBN 11.2, made in North America. There are a number of CI4+ oils still made: Texas Refinery Corp, etc.

Go to an auto parts store that carries both M1 TDT and RT6 and look at the API Donuts. There is a difference between the two. That's all I'm saying. I know that M1 TDT is CJ4 qualified, but the extra endorsement in the API Donut must mean something.

The only AMSOil that is CI4+ qualified is a 15w40, and I wanted a 5w40 for lower viscosity on a cold start.

Where is this oil available? Is it a house brand for Co-Op farm stores? (Nothing against it, but one my constraints is to be able to buy my diesel truck oil at many locations without it turning into a "Quest for the Holy Grail".)

Amsoil AMO (10w40) and HDD (5w30).

I'm well aware of all that, but I'm talking about the API Donut, not the list of approvals that the oil manufacturer puts on the bottle.

That PetroCanada oil looks like some good stuff!

The PC oils will likely be easier for you to find in the States than will our Co-op oils. The Co-op oils are regional enough in Canada, let alone in the States. I'd be surprised if they were even available in the States at all.

 

[A_Harman]

I inquired with PetroCanada and found a source in Michigan about 40 miles from my home. I'll seriously consider it for my next oil change.
