Oils that lessen consumption

[Drew99GT]

Just an update. Now, I could care less about the oil consumption! I just filled up my gas tank; the tank I filled was from the drive I described in the 1st post. Now, this is going up 7% grades/mountain passes at 65-70 mph through the CO mountains. I wasn't exactly driving easy, I was pretty much hammering it on the uphill parts. 43 miles per gallon!!!

The darn thing is only rated at like 35 highway. Whatever is in Maxlife, it really woke up the gas mileage. I did change plugs about 2 weeks ago as well but the old ones only had like 15K on them.

When morning temps get in the low 40s and 30s and then down from there in the dead of winter, 5w-30 makes a HUGE difference in fuel economy vs. 10w-30 in this car. And it's peppier to when the engine is cold.

Hello, new here but i saw your post, i too have a 1994 corolla that also loves its oil, from my expirience and the 3 engines sitting in my garage i can tell you its more than likely your piston rings causing the oil burning the oil rings get hopelessly stuck in there ring grooves and then you have consumption, also you will probably find almost perfect compression, but with little difference between a dry test and a wet test, simply because the compression rings are all ready "wet"

Hmmmmm, I've done 3 Auto-RX cleanings which are supposed to clean out the rings. Perhaps a piston soak with a strong solvent will be next on the to do list.

Man o man, my little 94 Corolla is just eating through oil like I eat a steak. Arggggggggh mmmmmmmmm

I recently put in my free Maxlife 5w-30 and had to drive into the mountains, mostly at 70 mph and she's gone through a quart in about 1,000 miles. Some of the consumption is likely from high vacuum on downhill streches; I was engine braking at 75mph at 3500 rpm (still in 5th, this thing is like a weed whacker)on Interstate 70 and my catchcan was practically full after the drive.

Which oils have you tried that really helped lower consumption? I'd like to stick with 5w-30 at least for winter. Maybe 5w-40 Rotella? As soon as it goes CJ-4, I'm going to try it and see how much it consumes.

to answer this simply, buying a lubricant that makes no sludge at any operating temperature will keep compsumption to a minimum.
no way does crude oil meet this standard, have you been sludged? like the Castrol commercial, they have a new anti sludge formula, what I wonder is what where they selling before the anti sludge formula?

you hit the nail right on the head sir

crude dino oil does not lubricate the ring land area very well if there is varnish and caked on API certified oil on the piston does it?
using true PAO synthetic oil avoids this baby momma drama
under your hood

eliminate the source of sludge and the cleaner may work

NO oil will function ideally in the ring pack if the ring pack is already gummed up. Duh.

Ok you have a point there but you did say ideally, wich is true to some degree but NO crude based oil can lubricate this high temperature area without being consumed to some degree, but a lubricant that does tolerate the heat in this area will clean out the varnished API certified oil right on out of there.

If you do ever want to go the HM route, Supertech 10W40 HM seems to show some good specs for about $7 per 5 qt jug.

ah, sootyoil the troll!!!

I'm the 2nd owner of this vehicle and it likely wasn't maintained to my standards.

Why does my pops 98 Blazer barely consume a drop with over 200,000 miles, all dino?

And no sludge. In fact, the valvetrain area of the cylinder head looks like a fresh casting. Clean as a whistle.
