how to stop oil burning?

[tlong831]

my 94 corolla burns about 1/2 a quart ever 1000miles .. what can i do to lower this consumption?

[broke]

I am pretty new to the world of toyota, but 1/2 qt over 1k miles doesn't sound so bad.

As long as you are not leaving a smoke screen behind you should be ok. If it really bothers you put a can of restore in there see if that helps. If you really are burning oil time for new rings.

However this is just my opinion

[toyomoho]

The industry standard for excess oil burning used to be 1 quart per 1K miles. Have someone do compression or leak down test to determine it the problem is rings, valves, etc. Any oil leaks, white smoke upon cold start up, PCV system OK? Might try a little heavier engine oil.

You loss rate is not that bad, bad is 2 quarts per 1K miles.

I was losing a qt every 700. I tore it down and replaced t he rings. Now I burn nothing at all. Rings were very gummy. If that's the reason you're burning you might want to try what someone else suggested after I had mine torn down. I don't know if this works, but someone said to pour 1/2 a bottle of Seafoam in the oil and drive it for 500 miles, then do an oil change. That will supposedly clean up those rings. That's assumiing of course that gummy rings is your problem. If it's valve seals, well then those probably need to be changed out.

Switching to synthetic after a good flush may also help, but again there are no guarantees. First you need to find the source of the problem.

If it blows smoke upon startup after sitting overnight, it's valve seals. If it blows smoke when you rev, it's rings.

Change out your PCV b4 you do anything though.

Good Luck

The saturns have a similar problem and they use this method to fix it. Remove the spark plugs and crank the motor so that you can pour at least 3 or 4 ounces of seafoam or marvel mystery oil in each cylinder. Put the plugs back in and let the car sit for a day.Remove the spark plugs and crank the motor until the fluid is out of the cylinders. The solution will often free up the rings and improve the oil consumption. It is a cheap fix.

Take out all the oil, so theres none there to burn.

^ That's what I did in my '92 Camry with 245K miles. Then I quit putting gas in it 'cause it just kept burning it too. So far it still rolls down hills just fine.

"Free up the rings"... lol, rings dont get stuck to begin with. Only time I've seen rings "stuck" is when the piston dome collapsed due to detonation squeezing the rings in between them. Also rings dont move, they stay at the same position all the time, thats why you place them with the gaps on the opposite ends of the piston circumference.

Major causes for burning oil is valve seals or piston rings. Neither really has a quick fix.
If its the rings, re-hone and re-ring the engine.

If its the valve seals, replace them.

LMFAO dave, that was hilarious, and i agree with hlashmn there is no real quick "fix" BUT u can slow it down, as said about, but in a heavier oil, and throw some lucas into the mix, bout 1 litre, anyways hope that helps

[Flashmn]

there is no cheap fix. You cannot add metal and steel to missing and worn away metal. YOu can at best thicken oil. With thicker oil. YOu must replace worn parts with new parts. I guess some people refuse to accept that.

[tlong831]

thanks for the input everybody
i know there is no quickfix
i use quaker state high milage 20-50
and i have been changing my oil more often it seems consumption is going down

and i heard lucas is crap i checked out bobistheoilguy.com

im just going to change my oil every 2000 miles

[freakinbox]

doesn't sound all that bad...
I say first of all look at the age of the car. Thats not to bad for something that is 13 years old
