Sorry for the semi-hijack:
The Magnatec is in the same league in the motor and on the road or better than QSUD. I am no BP fan boy but this MAGNATEC ILSAC stuff is special sauce - and the 5w20 Synthetic is even better than the 5w30 SS.
Speaking of glorious QSUD, The Nissan dealer in Stratham dumped my wonderful new pan of 10w30 QSUD (non dexos) at about 3K miles into an OCI - and I specifically mentioned NOT to do an oil change! (they were doing a tranny pan drain and a Xfer case and 3rd member lube.)
The dimwit ne'er-do-well also looked at my engine Air filter (even though I had a big white packing label across the locking tab with the install date of 8/16) They didn't clean it just thrw it in the box NOT INSTALLED and closed the lid. Now I have 300 miles of operation with NO FILTRATION. I noticed a hesitation at throttle tip in, that's what directed me to look at the air box.
