I can get 15-40w Rotella T for 2.19 a quart or 8.75 a gallon.
Is this a good price? (about 10 cents more for delo 400)
I here a lot of good things about Rotella T but, I've been thinking Delo 400 cause my friend's trucker dad has high praise in it.
So which to pick?
That's a darn good price for delo. Delo is what I run in my diesels. I go 6-7K miles on it in my 4BT no problem. Anything else I've tried I've changed at 3K or less when it didn't look too hot and pressure was dropping.
