Good deal

First day driving oil pressure way better, motor knock went away. The real test and why I purchase this is to remove slug with use a flush.


Good Buy

I use Castrol in my 1998 4Runner with about 170k on it. It runs really well and I've had no issues with my oil.


Best conventional oil out there

I've changed my oil regularly, including the filter and my 1994 Ford Ranger just hit 300,000 miles, and I never have to add oil between changes. Does it get any better than this. This oil is $ 5 a quart at all the auto parts stores I've checked .


Great price...

What a great price, Autozone, Advanced Auto, O'Reillys would not even match the Wal-Mart price. They all said "We don't match Wal-Mart".


Great product!!!

It cleaned out the old sludge build-up in my 2000 Toyota sienna. I am very impressed and satisfied with the results form this oil. Buy it and I think you will be too.
