Oil was in the vehicle for approximately 18 months. Had added 16oz can of Restore. Oil filter was a Napa Gold and air filter is K&N. Most recent oil change was done using SuperTech 10w30 conventional and a Motorcraft oil filter. Thank you.

SuperTech Heavy Duty 15W-40 CK-4 / SN. 10.0 TBN and 1270 ppm Zinc. It's cheap, has a passenger car rating, stands up well to long storage intervals and has plenty of zinc for the flat tappet cam. As long as the sump temp is 20F or above when starting it would be my choice.

@teambeechstreet Out of curiosity, did the restore do anything for you? Any difference?
Nah, no difference. I originally added it due to some blue smoke on startup after the truck had sat for awhile. Still blowing a little blue smoke even with the restore. Buddy swore by the stuff on his Ford E-250 with the 5.4 engine.

Valve seals seem to have failed if that's the case. A thicker high mileage oil would have had a better chance at having an effect than restore. In your friends case his bores were scored and restore can help fill in a bit.

Restore is effectively a soft metal slurry that temporarily fills in scratches/scores which, on an engine with damaged bores, can improve ring seal and reduce oil consumption. But of course that engine is already on its last legs and the effect is only temporary and also makes oil analysis basically useless because of how the soft metals skew the results.

Your issue sounds like valve guides or seals, as Javier noted. In this case, an oil that MIGHT help would be Valvoline Maxlife. I would also expect @High Performance Lubricants oils, which have considerable ester content, to help in this respect, though I don't think anyone has ever asked David about that direct that I can remember. Their 0W-40 almost immediately stopped the smoking my son's dirt bike was doing (Yamaha 4-stroke), and it has never returned.

You ought to add that to your title of your thread. Supoertech was not the reason for the crazy numbers, Restore was. Very misleading.
