Higher weight oil

[smetzger]

I have 285k on the clock. Oil consumption has gotten quite high. 2.25 qts over 3000 mile period.

I use synthetic 5w30 with a oci of 4000 miles.

I want to try a higher weight oil to see if it cuts down on the consumption.
What weight would you recommend?

10W30 regular dino oil...

Burns off slower, costs less...

Walmart.. Cheap stuff...

Throw some seafoam (or equivalent) in your engine oil and washout all the crap and help keep your oil rings from seizing completely...

Agreed! You could also use Diesel, ATF... pretty much any type of a detergent. Run it for 10-15 minutes, then dump the oil. Don't change the filter yet. Then fill with 3 qts of cheap dino-oil and a quart of ATF/Diesel/Seafoam/whatever and do it again. Then drain it again. You can repeat as many times as you like or until it comes out relatively clean, and then change the filter. You'll be surprised how nasty that "10 minute old oil" can be!

Then use some regular 10w30 or 10w40 and see if it makes any difference. But i'd plan on a rebuild, replacement motor, or new car sometime in the near future if you're burning that much oil. I have run regular 10w40 in my car since I got it a few years ago with no issues at all on the heavier oil. 255k and doesn't smoke, leak, or burn a drop of oil. Then again I live in GA where it almost never gets very cold, so the thicker oil doesn't hurt anything in the winter. And if it's cold, I just don't leave the house. It snowed this winter, like 6 inches of snow! First time we have had snow on the ground since 1987. The 4wheelers got a LOT of use but my car didn't move for about 3 or 4 days until it all melted away lol

Ya I'm getting there. I use about 3 quarts before my 5500 mile oil change.

Mine might use a bit depending on gas pedal abuse but my oil changes are more time based than mileage since it isn't the daily driver..............
