    Phillips XC

    Posted by John Majane III on Oct 04 2023

    This is an excellent aviation oil. Two years ago after a cylinder change the shop put it in my engine. I had been using Aeroshell 15W50. I immediately noticed that the oil leaks from my E-225-8 were substantially reduced. No difference in performance, oil pressure or anything else and it is less costly.

    Oil works great for us

    Posted by Ed Borstel on Jul 10 2023

    Switched from Aeroshell straight weight oils to Phillips multi blend when Aeroshell was experiencing supply demand issues. So far we are pleased with the product and the price. It seems to work fine and is a bit less expensive.

    We switched from straight-weight Aeroshell oil to the Phillips Multi-viscosity oil due to availability and price. So far we have been pleased with the performance of the Phillips product.
