Quaker State Defy on sale at CTC.

[Case75]

$4.69 a quart. Saved $10.50 on 5 quarts. This oil is rated SL which is good for us guys with flat tappets. I checked and the Rotella is now CJ rated instead of the old CI; not good enough anymore. I should go back and stock up.

For some reason the Americans are paying nearly double. With my GM discount it's $6 and change. I always used it in our flat tappet engines once I heard about the lowering of ZDDP levels.
