Thread: Stuck oil rings & engine flush?

1. Could that actually free up stuck oil rings?
2. How often do you get stuck oil rings on V8s?
3. Can stuck oil rings cause high oil consumption?
4. I don't feel 100 % comfortable driving around like this... Your thoughts?

He did WHAT???? and told you to drive for HOW LONG????

Stand by for some broken rings and even MORE oil consumption. That is NO way to resolve an oil consumption issue IMHO.

Not happy jan.

Ill back that with a great big

WTF?

theres some things that an additive can sort between oil changes.

sticking or rooted rings aint one of them.

If hes added one of the "metal rebuilder" addatives stand by for a new engine after its been "fixed" for say 10K Km if you're lucky.

find out what he added.

Boost Engine Flush, the kind you're supposed to run in the engine for 10 minutes before changing the oil.

and hes told you to drive around for a tank of fuel with that in the oil?

you must get some seriously bad economy...

at least it wasnt one of the metal rebuilder ones I was scared it was going to be..... They make a big mess of oil galleries. oh and bearings, cam surfaces..

Why do you say I must be getting bad fuel economy?
Shall I dump the oil now? Or has this got a marginal chance of helping?

He must think you go through a tank of fuel in just over 10 mins

Has a very low chance of helping in my experience.
You may as well give it a snort of baking powder as well

well if it takes you a full tank of fuel to run the engine for 10 minutes....

there might be an outside chance that if the oil rings are carbon fouled that the addative might just maybe lift enough of the carbon away to let them free up and move about enough to do their job again.

the problem is that if that works your not fixing a cause your curing a symptom.

without fixing the cause of the problem that got the rings stuck in the first place its just going to happen again.

how long you can leave that stuff in the engine depends on whats in the flushing agent that makes it work.

Personally I'd suggest that the packaging says 10 minutes for a reason.

I'd give it some stick on the highway for a few K's and see what happens,thats a common fix for old peoples cars,either that or some ajax down it's neck. Pat
