Yes i would think so if there only that much difference although the biggest plus side of the marvel oil is the camphor in it which is a great de-carbonizing agent and cleaner. I personally wonder if it would have a affect on the plastic... ? dunno when i order from dwyer they ship it like yesterday...
the granger stuff is actually the dwyer stuff same part number but seven cents cheaper!!!!
for the 4 oz.
So far so good on my Dwyer/Marvel... for future reference.
I bought mine (mano) off eBay, and it was complete sans oil!!
(I just checked the Grainger site. Their oil is $10.68, is that the one you use?
The Marvel is less than 3 bucks at your auto supply house....)
