I work for an oil and fuel distributor and was lucky enough to find a healthy stash of delo 15w40LE. I my search I also found a rib (55 gallon) of delo 15w40 multigrade.
I have a 2002 duramax diesel with absolutely zero emmissions.
Should I buy the multi grade rib or just stick with the delo LE?
Thanks.
