my lx450 seems to burn oil. Suggestions?
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?

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.

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. __________________ 70 FJ40-sold, worst day of my life 79 TOY 4WD pup-stolen, 2nd worst day of my life 91 4Runner 4WD-burned to ground, 3rd worst day of my life 83 FJ60- suckiest day of my life 97 LX450, 221k, non-locked.

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 |

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

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.

Oil Burning
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.

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. __________________ Robert Callaway '03 LX470 42k mi. - The Smooth Ride '94 FZJ80 207k mi. - Bone Stock and Locked, less the OE roof rack, add a D31M '85 FJ60 - Sold |

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

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.
