Old subject: engine oil loss

Peter wrote

without mentioning the specific brand for fear of it being interpreted as spam, my solution was to switch to a full-synthetic 10w-40 as any

I have since totaled our 98 Trooper (98,000 miles), but it was using a quart every 1,500 miles or so. I used Mobil 1 10W30 since about

The last few oil changes, I found that by mixing 50/50 of Mobil 1 5W30 and Mobil 1 15W40, reduced consumption considerably. Consumption dropped to about 1/2 quart in 2,000 miles, which I consider much better. When it would use some, I would refill with 15W40.

YMMV.

I'm switching to half-synth 10w-40 as full synth at my mileage seems like total waste of money. Will report how it behaves.

My trusted mechanic proposed another take on this: spark plugs seem to be clean (so probably is not burning it off), but oil filler cap lacks rubber seal. It could be that oil is slowly being forced out thru filler cap, and since it happens only when driving there's no visible leakage under the car. Any comments?

It ALWAYS looks like hell. Whaddya expect after putting in 1qt every

You'll see streaks and dirty gunk on the engine itself, so unless your engine bay looks like hell it's probably not that.

Sorry for the empty replay before.

try hiring/borrowing a low pressure steam cleaner/waterblaster and throuroghly cleaing the engine bay, and after topping up the oil wipe down any new spills, see if a lot of gunk builds up again.

I have been using a full synthetic, with a "1" in it's name, for over 3000 miles in my 98 Trooper. I have used 0W-20 as has been suggested in this group, and in other forums, as the cure for this oil control ring problem. My experience so far: a waste of money. The synthetic has made NO difference whatsoever in my Trooper's thirst for oil. It still has required an additional quart every 1000 miles or so, just as it did on regular dino oil. I have been adding more M^&*%-1 when it got low, but my patience with this "cure" is wearing thin and I suspect the next quart is gonna be back to dino oil.
