    I like the product and Petroleum's quick and efficient delivery! However, I don't like that it's only available in a more costly 6 quart case. I preferred the 12 quart case at a slightly less cost.

    PSC is my new supplier for Aviation oil

    Posted by Ed on Sep 27 2019

    Ordering was, delivery fast, pricing was below all others when you considered the total costs. I historically was using another PA based oil supplier, their price was quite a bit higher than PSC.
