What is your VX Oil Consumption in 1000 miles? Part Deux.

[HeckaTrebeka]

Yeah, noticed early on that my VX was consuming about a quart every 1000 mi. Thats been going on for about the last 4 years. However when I checked it last time, a couple weeks ago, only needed 1/2 a quart.

OMG, its healing itself!

Could by that you're driving differently? Different speeds? I noticed that if I keep it at 60 mph or lower, then I don't burn nearly as much oil than if I hit 70 or higher.

Possible, but I always thought that would only effect gas mileage? But no, I drive pretty consistantly.

When i first got my VX the PO said he ran synthetic oil. I ran castrol 5w 30 synthetic. I went through around 2 1/2 quarts in 3,000 miles. I did not change the pvc valve. The last oil change I changed the pvc valve, switched to Valvoline 10w 40 High Mileage non synthetic oil. I have around 1500 miles on it and only used about a 1/2 quart. Not sure if it is the new pvc valve, (old one did rattle like it was not plugged up) or if it is the thicker oil, or if it is because of the high mileage non syn. oil, or the additives int the high mileage blend?
My VX has 120,000 miles on it and has the original engine as far as I know.
I have no problems with it starting parked outside in single digit weather with the thicker oil.

I have long considered the possibility that it is synthetic oil that causes oil burning.

After discovering the oil useage I swithed to 10W40, not the High Mileage though. Didn't notice any difference. Even a new PVC valve had no effect.

Anyway, the multi-grade oil shouldn't give you a problem with the low temp, just don't try that with straight 40W. I did that once when I was a dumb first time car owner. Oh well, it started again in the Spring, lol.

Could be, but I have never used synthetics. Crap, it could get worse?

i dont use synthetic and all mechanics that i have talked to say with this problem synthetic might be a little better but would almost certainely make no difference just cost more for the oil - apparently the structure of the oil makes no difference its how our engine circulate and cool it - if we had no emissions comtrols on this vehicle it might be another story however

Mine just recently started consuming oil.

I have an idea...

There is an engine flush product on the market that is basically a solvent that you add to the crankcase will full oil level.
You run it at idle for a few minutes, then drain it and change the filter and oil.
It's intended to remove sludge and other build-up.

Wouldn't this help clear the oil drain holes on the pistons, since that is the culprit anyway?
Thoughts?

I like the idea, but I would trust one of the BG products first. They have a few that are listed to do the same thing.

Doesn't the stuff many forum members say they've used (Seafoam and a Amsoil Engine flush) do the same thing?

I've used Seafoam once and the Amsoil once.

[Ldub]

..

I've used seafoam every 2-3 oil changes(as a crank case solvent, before draining the old oil) for most of Suzy's career as my daily pony...she still likes about 3/4 of a quart every 1000, whether it be lead foot'n around back & forth to work, all hiway to & from Moab, or grunting up & down trails...

She likes 1.5 qt every 2000...so...basically 2 qt between changes.

drain back holes in rings are supposed to be lacking in some VX engines; I thought it was limited to 1999 versions but from the poll looks like not

[psychos2]

when my vx was using a lot of oil it was the pcv valve. I had put a new pcv valve in and used 2 qts in 1000 miles. got rid of the pcv valve by plugging the hose and putting a filter on the valve cover. went back to 1 qt every 3000 . with mobil 1 synthetic. there is no baffle in the valve cover and if the pcv valve sticks open it will suck oil and burn it . you will not notice it because the cat will burn it and no smoke will show in the exhaust. shawn

my 99 astral burns so much oil I think they thing just wants to regulate it's oil changes!
