Best Value Around

This had to be the best value around, not a synthetic product but it is a very good conventional oil.

How much zinc is in the oil?

I searched high and low online search I can not find zddp (zinc )level in the oil. I have not used it yet I'm sure it will work ok.

My problem is the price doubled!

I motor oil is good as any other motor oil but before COVID this was $21 a case, now it's $42 a case. Motor oil didn't catch COVID, nor did livestock, lumber and anything else, so why are the prices going up?????

Fast Burner

This oil burns very quickly in an older car - about 3-4 times faster than Quaker State. Definitely not worth the slight savings in price.
