My boss has an older Wrangler. Over the years it has started to use quite a bit of oil. I am putting 15w40 in it now.

Would a straight 30 or 40 be a better choice at this point? Rebuilding or replacing the engine is not in the cards till summer.

At temp the 15w-40 will be thicker and is probably a better blend than straight 30 so less volatility.

When cold the 15w is thicker too! Tested in a paper cup outside this winter.

Sometimes switching brands can slow burning. Otherwise move up to the 20w-somethings!

Is it a 4.0?

In the Cali climate a 20w50 would be... passable? So thick it's nothing but a band-aid, but you already know that. I'd be curious to run some Rotella 30 wt. and see what it does.


I like Chevy and Valvoline.

I'd say it cannot hurt to try.

Do some role playing. Pretend you are a stereo typical used car sales guy. White loafers and belt, pencil mustache, combover, etc. Fill it full of Restore.

its the pre 4.0....carbureated 258 with 190k on it. I rolled bearings into it 2 yrs ago because they were down to copper and rattled at higher rpm. Got lucky and that worked but its getting tired.

As long as it's warmer than 40F outside...go for it... and let us know if it helped.

Use 15w40 with a quart of 20w-50, it will thicken a little bit, but not enough. I think this will let you see if it is good.

Just buy the cheapest oil.
You can get API "CJ" oil at Atwood's Farm & Ranch for only $6 a gallon.

I had an old Chevy 283 that burned a quart of oil every hundred miles.
All I ever used in it was USED 15W-40 Diesel engine oil

Straight weight SHOULD have lower consumption due to lower volatility, and SAE30 is fine below freezing (not quite sure where the 40F came from, that's wrong).

If you can get it cheap, use it...but el cheapo 20W50, provided actually an API approved oil is fine too...I'd prefer a lighter straight for consumption, but try them.

Back in 1987 (my gap year), I worked in a service station, and the work vehicle was a 1973(?) ford Falcon ute, with the 250 with integral inlet manifold...it was a hideous oil burner. 3-400 miles per litre.

I convinced the boss to try a product on the Shelves, Nulon (Teflon) E10 worn engine treatment. It reduced consumption by easily 75%. It's different to any of the "permament" teflon treatments, is was a clearly visible colloidal looking stuff that had to be replaced each OCI.

OR go to Walmart and get 5qt jug of SuperTech 20w50 for $11.XX. But I personally would give Valvoline Max Life 15w40 a try. It's a High Mileage HDEO. Best of both worlds right there.

1qt every 600 miles or so. Not terrible. It has slowly been getting worse over the years.
