Chevron Delo 400LE VS Chevron URSA VS Petro Canada

[Johnson615]

What appears to be the main differance in these oils? Im trying to make a decision between the three for our fleet of dump trucks with Cat C-12,C-13,C-15. We generally only run 15,000mi service intervals. We can buy the Ursa for $6.84gal and Delo $9.74. All i can figure would be the base oils.

Also posted is Petro Canada Duron E. price on it is $7.78 but it didnt really impress me.

Other than TBN what stands out
What are you guy's thoughts. Any opinions are appreciated Thanks

Ursa looks good for the money, a touch less intial TBN then Delo.

I agree 100% that the Ursa and Delo 'look' much better on paper than the PC oil.

...but don't count the Duron out - PC is one of the best oil blenders in NA, and they know how to make quality oils that will get the job done. Their base oils are the best group-III's you will find (and yeah, that includes SOPUS and Chevron group-III's...)

It's said that the new oils use additives that aren't picked up in analysis. Is the same true for HDEOs?

Does the Mg in the Chevron pack make up the difference to the Ca in the PC?
