Is Chevron and Shell related?
If I can return a partial case for full refund, why not?
I would be getting the same brand of oil,wont have to mix it for winter and gaining 4 quarts.
I thought mixing grades was frowned upon.
Why all this talk about diesel oil in gas powered cars?
Is there something I'm missing?
I don't want to go beyond 10WXX if I don't need to, and I think I do.
my car is not burning or leaking at all.
What about the "As thick as necessary, but no thicker" rule?
Wouldn't that apply to Delo 15W40?
Why do I have a feeling this getting out of hand, beyond what I have been asking.
I don't think everyone is reading the entire thread or following along very well.
No one every replied directly to my question of what to do with the 20W50, but since Costco will take it back and give all my money back, that is no longer an issue.
Now maybe somebody will answer my questions regarding Chevron/Havoline.
Thank you and have a great day.

Doesn't Costco carry both Shell(Formula Shell) and Chevron(Delo)? I suggested Delo because it is an outstanding oil and is thinner than the 20w50 you have been running and can be had very cheaply at WM.
If you don't want to use the 20w50 than return it.
Our local Costco's (3 in our area) doesn't carry Shell oil.
I think some do, depending on region.
I returned the 20W50 today.
We have a business Costco Warehouse here and they also sell PYB & Pennzoil full synthetic 10W30.
