Duron E 0-40

Has there been any testing done on Petro Canada Duron E 0w-40?
Is it a good oil? I have an 08 cummins diesel truck.

Welcome to BITOG.

There has been extensive testing done, it's an API CJ-4 oil.

Great stuff! Use without question. All the big construction/mining and oil Co.'s use that stuff up there. It is a 0w40 that can take a pounding.

Thanks for your help guys

I ran it last winter in my Duramax. It was a good feeling when I had to start the truck at -30C not plugged in. It just fired right up.

I'm running it right now, have about 1000km so far on the oil and have actually noticed a lower engine temperature.

I was going to send in an oil analysis on some new stuff but haven't gotten around to it. Still waiting on my sample that I sent in from some 15w-40 I was running.
