Engine/Transmission (1998.5 - 2002) 5W - 40 oil in 99?

[CElliott]

Hi,



I am pondering using a 5W - 40 in my 99 24 valve engine. The oil in question is Duron Synthetic made by Petro Canada. According to the oil it meets CH-4, CF/SL and SJ categories and exceeds CG-4, CF-4, CE, CD/**, and SG as former categories. The oil has a sulphated ash content of 1. 37. The fella at the high volume pump station says they use it in all their big rigs now and have been for the past year. The oil does meet or exceed the Cummins CES 20076 specification along with a whole host of others by Capterpillar, Detroit Diesel, Perkins, etc - which doesn't mean a whole lot to me.



I live in a northern community (Fort McMurray, Canada) and their isn't a lot of choice for places to go, but any suggestions would be appreciated.



Will this oil work for me?



Thanks,



Clint Elliott

It is a great oil. I have been running it in three Cummins with great results. I have an read a published article that put it up against Delvac 1 and it did extremely well and for all practical purposes performed equally as well as the Delvac. The tests completed in the article did show that the Delvac would hold up longer but the PC Duron 5w40 can easily go 10k miles between changes.



FWIW - I think a 5w40 is the perfect oil for the northern climates.

After seeing first hand the quality of Petro-Can oils I would say not to use it. We had a batch 4 years ago of 0/30 that had separated and got real lumpy. All the rep could say was that it needed to be shook- up before poured.

Some may think that you are in an Iceberg in Fort Mac in the summer but that is far from the truth. I've lived there myself and it is a warm as anywhere in Canada in the summer. [the winters are a different story]. Nothing less than a good 15/40 for the summers and Esso xd3 0/40 for the winters. The Esso oil doesn't stink as bad as the Shell. If you can handle the smell of Shell it is also a great oil.

If you are having trouble finding the Esso or Shell go straight to the bulk dealer that supplies the fuel. The little convenience stores don't stock much if any and you will pay dearly. Crap tire and Wally world are a waste of time.

I was not suggesting the 5w40 was necessary for summer months in a northern climate but for the ease of running the same oil year round the 5w40 is perfect IMHO. It will really shine during the cold starts in the winter months.



FWIW - There are quite a few guys running the Duron Synthetic in the VW's, which are much harder on oil than our Cummins, and their oil analysis are coming back exceptional after 10k miles.

Thanks for all the info. I think I will give the oil and try and see what happens.



Thanks again
