Oil burner no more!

[pistolpete]

I have a '98 Honda Prelude with 135k on it that has burned some oil for a while. Since the wife began to drive it the burning got worse. So, last oil change I put in 10w30 rather than the 5w30 and it still burned. Before I took a 960 mile road trip I topped it off with 10w40(1/2 quart) and added RedLine fuel system cleaner.
No oil burned on the trip! On the same trip in the past, I would burn 1 full quart. I belive the Redline stuff freed up some deposits by the rings.
What do you guys think?
Oil used is Amsoil.

i dunno. i would try autorx to free up the rings. my integra burned a quart to every 500 in town and a quart to every 300 on the highway. when i ran the 150 mile clean phase i had to add only hasf a quart for the 1500 and none since. 95 acura integra with the b18b engine.

Could it be that the long trip itself freed up the rings?

I'm thinking the thicker oil is what did the trick. My car runs 5W30 and uses a quart every 3 weeks. I tried topping up with 10W30, same thing. Topped up with 10W40, the first week I used hardly any oil at all, then it went back to normal.

ARX it. I wish to heck I'd been able to use it on some old oil burners years past. Get those rings freed up, UOA it, and get a good recommendation (DYSON ANALYSIS) on what to use next.

I used ARX in my Tercel with zero results.

So, if she continues to not burn oil, what do you guys suggest I put in at the next oil change? That change will likely stay in until the cold weather returns. 10w30, 10w40?
Also, I find it hard to believe that a 1/2 quart of 10w40 had much to do about it. The car runs 4k rpm at 80mph, and I rarely slowed down to that speed(made it in 6 hours, that is one way 480miles, and that is counting stops for gas and ***). Again, the same trip in the past burned 1 whole quart.
Anyway, thanks for the help, and 10w30 or 10w40?

Use a dino 10W-30 and start an ARX clean and rinse program, and include a high-mile power run during both the clean and rinse phases.

After the prescribed 1,500-mile clean and 2,000-mile rinse phases, stay with a dino and use a 3-ounce ARX maintenance dose.

If you still get consumption, maybe a 10W-40 is the answer. No consumption, go back to a synthetic, and see if anything changes.

I would repeat/use the same as prior... at least for another OCI. We/you would like more evidence that your fix is not temporary.

Some engines consume more with a 5w30 than a 10w30, although usually not much of a difference.

 

[pistolpete]

I think I will wait until this oil is done to decide what is next(about 4k more miles). It sounds as if you guys think the burning is not over, yes?
Well, I will keep you all posted. Thanks again.

Well that depends. Does the mfr permit 10w-40 in this model? If not, you should use High Mileage Pennziol or Castrol 5w or 10w-30. Thickness is inbetween regular 10w-30 and 10w-40.

Sounds like the fuel treatment did a good job. Do you still use it?

It's also possible you have a small coolant leak that only enters the oil when high speeds occur. That could keep the dipstick level up. It happened to me on a long east coast trip in 2005. I didn't know anything was wrong until the engine idled rougher for around 1K before changing the oil. When I changed the oil, it was dull & shiny clouds floating on top of the oil pan. When I refilled with new oil & drove it ever since, the idle returned to super smoooth.

I have the GM 4.3 engine with slight coolant leak. The faster I go -- the better chance it leaks. So now I shortened my OCIs to 5K synthetic instead of 7K synthetic. I may someday need to shorten that more - or get it fixed. I'm running the coolant tabs now.
