my lx450 seems to burn oil. Suggestions?

wildman326 · 09-08-08, 12:54 AM

It seems to burn quite a bit. It's got about 160k.

Does it need rings?

Is that super hard to do? I've pulled the motor on my old 89 toyota truck a few times, replaced it's headgasket, rebuilt the rear end, and rebuilt most of the tranny, so I'm fairly competent mechanically . . . .

Er is it actually burning oil? Could it possibly be leaking oil instead?

F0RSAKEN · 09-08-08, 02:00 AM

How rapidly is it losing oil (burning or leaking)? Mine eats about a quart every 4k miles or so, and I know a few other members' rigs do as well.

NLXTACY · 09-08-08, 02:39 AM

I've been lucky. I go through half a quart every 6-7k.

But you NEED to verify if it comes from a leak before you start linking about tearing anything apart.

Synthetic or conventional? Try some Shell Rotella 15/40 and a Wix filter. I swear by this combo and run it in everything I own. If this oil "disappears" I would say you might have a ring problem. If it doesn't smoke any, who cares, just keep topping it off. Beats the hell out of the price of a rebuild.

It leaks some, but not enough to drip onto the ground.

I'm using mobil 1 synthetic 10w30

I am using this same oil as well. You might want to try the High Mileage variant of M1 10w-30 or try a XW-40 weight oil.

Good luck.

My 1994 did not like the Mobile1 you are using. I switched to the Rotella mentioned previously and all was well.

DocLX450 · 09-08-08, 06:49 PM

I've tried all the above, but when it burns, time for ring job. I just don't see any liquid at this point will help. Mine was burning at 150K.

Are you doing your own oil changes? Make sure your shop knows these vehicles take 7 quarts. My oil light came on and after I stopped panicing, I looked at my last receipt and realized I was only charged for five quarts of oil. My LX still burns about a quart between changes. Five quarts minus another quart give or take plus a slight incline put the light on. Food for thought.

super90 · 09-09-08, 06:45 PM

Mine "used" more oil with M1 10W-30 too. I am in Texas and switched to 15W-50. Consumption is lower, maybe a quart per 3k mi.

My indy worked at the Lexus dealership, maintained a lot of LX450s and said many trucks used oil even when new. Not to worry too much.

I would definitely do some analysis with the different oils and viscosities before declaring it needs serious work.

john_eckels · 09-09-08, 09:01 PM

I switched to the M1 High Mileage and my oil consumption went down significantly. I now go through a quart every 3-4K

e rock · 09-09-08, 09:46 PM

The P.O. of our LX had a complete engine rebuild done at the Lexus dealership at 138K for "excessive oil consumption" to the tune of nearly $4K. It doesn't seem to use any now at 170K.

THIS THREAD IS WORTHLESS WITHOUT KNOWING HOW MUCH OIL IT'S CONSUMING PER 1K MILES!!!
