Oil that produces the least amount of exhaust smoke?

I'd check the stem seals, if they're bad replace them. While you're at it run the RVP for the four OCIs they recommend and see what happens.

Be sure you’re blasting Junior Brown through the stereo when you do.

Thanks, I’ll look into it. I’m pretty sure the engine is just worn out, this car was a highway patrol cruiser in the 80s so it was probably beat on. Here are the leakdown results. Ironically, the car runs great and only seems to smoke when you accelerate from a stop. It blows out a puff, but there’s no smoke during cruising, wide open throttle, downshifting etc

Awesome ride! As a retired Highway Patrolman, I can absolutely guarantee it was "beat on." My old patrol cars were either at a stop or floored. Amazing what a modern vehicle can withstand, I sure pushed mine.

Love the car. Brings back alot of memories.

And…..never shut off.

I run 20w-50 weight in lawnmowers that burn oil. Definitely takes longer to burn off than 30wt.

I have a 1984 Ford LTD former police car with the 5.0. There is a little puff of oil smoke upon acceleration and occasionally upon start up. I had a leak down and compression test done and discovered that the rings are worn and there is some blowby. I will be rebuilding this engine shortly. In the meantime, which brand of oil generally produces the least amount of smoke? From my understanding certain additives can increase smoke. I am currently using valvoline Maxlife 10w40.

In my state yes, but in most states it’s not allowed. I actually have a letter from my Sheriff that I keep in the glove box in case any small town cops give me a hard time.

Synthetic smokes less. A cheap ebay or amazon catch can will help stop oil from being sucked back into the intake. See if your PCV lines are an oily mess and add a catch can if they are. Snake oil additives like Lucus help somewhat as well.

Thanks for the responses everyone. I really appreciate all the advice. Quick question, in addition to Valvoline restore and protect, would an Italian tune up be advised or unadvisable?

Such as this? https://a.co/d/5ufd8jo

running the Valvoline (Cummins) Restore oil that has faster cleaning and just switch out filters every 800 miles at first

I actually was watching a video on this oil last night. However, I can’t find anywhere selling it. Is it still on the market? If so, would you happen to know how I might could get some?

I’d try the oil additive ‘Restore’ in the silver can at a parts store. Uses soft metal particles to fill in worn areas.
If you are rebuilding the engine anyway, it can’t hurt. If it reduces the problem enough you may be able to put off the engine rebuild for a bit.

I'd put a borescope down the cylinders before doing that Hail Mary pass, as that stuff is only suitable for an engine truly on its last legs. If the bores are fine and it's just stuck rings, you are simply adding contamination and causing more damage using that stuff, wholly unnecessarily.

They don’t appear to be. I changed the pcv a couple months ago.

I used Restore in a 1991 Subaru that was a major oil burner and it helped alot. I'd give it a try. Drove the car a good bit longer before it died of terminal rust.
