2009 tacoma 249k miles...additives

Hi
i have 249k miles on my truck, I was thinking using the liquid moly to do engine flush and then use liquid cera tec.... its burning a some oil like 3000 miles...anyone used these products?

 

I've used the liquid moly hydraulic lifter fix in a can and it did seem to help on a Silverado. so it basically met the claim.
I'd be really cautious on an engine flush at that mileage and would just run a small amount of marvel at each oil change. If it does have a sludge build up and you knock it loose you could block oil passages and cause bigger issues.
Maybe check and see if its sucking through the PCV? do these have pcv check valves?
When you say oil burning are you talking about a gallon at 3k or a quart?

 

Yes, they do.

4 qts. in a gallon. If it burns 4 qts in 3,000 miles. Nothing is going to help that engine.


I'd just add oil when needed. Run it until it dies.

 

smart input. you work an office job like me or are retired im guessing!!

 

Lawn and Landscape.

If it's not broke, I don't fix it.

My point of view is, The truck is still productive. (point A to point B).
If I tear the truck apart looking for "a problem". I just killed it's productivity.
Plus, I don't like walking. Which makes the decision even easier for me.

 

i agree. often times if you go looking for a problem, youll find one. just keep on keeping on

 

Yeah. I agree.

The truck has 259K miles on it.
Burning some oil isn't rally a "problem".
It's to be expected. Pour it in and drive.

Life's short. Worry about other more important things.

 

I did a seafoam oil treatment (crankcase flush) and added liquid moly oil additive at the following oil change, truck has 150K. The flush worked well and resolved a couple minor nagging issues, the motor has no appreciable oil consumption, minimal drop in oil level across 5K change interval. I'm very happy I did the flush, there were some noticeable improvements.

The oil w/ flush that I dumped looked like black ink, it's typically a dark golden brown color coming out, it returned to the golden brown at the next change.

 

Leave the engine alone,all the additive crap never solves anything,it's just a bandaid fix.

 

If youre worried about sludge in the engine- Valvoline Restore+Protect oil seems to have good reviews.

 

This. Not going to fix leaky valve seals but if your oil control rings are gummy, it might work to lessen oil use.

 

I love blanket statements with zero to back them up other then the poster's "opinion". Lots of examples on here where flushes that have improved some higher mileage issues like oil consumption caused by gummed up rings. Sludge is not unusual in high mileage motors and since our engines have a rep for going allot of miles, tacomas aren't immune to the issue. I guess we should just let the sludge buildup since additive crap never solves anything.

 

Well you are entitled too your opinion with nothing to back up your big talk.

 

I have used Liqui Moly and Ceratec.

Not sure what your question is.

Oil burning is a problem. Oil is within the crankcase to lubricate. Not be burned.
Fuel is burned.
Engines are designed to burn fuel mixed with air to create power. Not oil. Oil is for lubricating.

Whether that be from a bad PCV, bad piston rings, bad valve stem seals, etc.
Pouring liquid into an engine with a failed component does not fix a failed component.

Audi has figured this out since like 2005. The 1.8T AMB had sludge found to be due to inadequate oil capacity. So they released an updated filter that was much larger, to increase the oil capacity. This solved the problem. They have been using large filters ever since, and not having sludge problems ever since.

In comparison, the Tacoma engine is over twice larger, with more cylinders, yet despite that uses a tiny filter with about the same small oil capacity.
I have noticed my oil not looking as good as I'd like it to, even when doing 5k oci with synthetic. That is probably a factor.
I am not surprised. The engineers did a lot of dumb shit.

 

I lose about a quart-tish every 3000 miles... perhaps i can add a bit of the flush, drain it, rinse it with cheap oil, then put the cera-tec in when i put the better oil in.

 

You can. That will also not fix a problem causing oil consumption if you have a problem causing oil consumption.

ceratec is a solid ceramic additive meant to provide lubrication in adverse conditions such as hard cornering on a track car and the technology is said to have been used in WW2 airplanes to let the engine keep running for some more time even if it gets shot out in a way the oil leaks out.

it is not for fixing oil consumption problems. Nor is it for cleaning.

there are products and oils that claim to have a cleaning effect. Valvoline Restore and Protect from WalMart is one of those oils.
