If you're consuming that much oil, it should be evident by way of blue smoke. This can be seen when accelerating after idling for 5-10 minutes, or after starting the car after sitting overnight. Have someone look at the tailpipes in either of those scenarios and let us know what you find.

No oil residue out the pipe. No blue smoke. No oil leak on the ground. No oil in the coolant.

Only concern is the low compression readings. Only one Cylinder was at 145. Five cylinders at 140 and the other two at 135 psi.

So even if it happens that the screwed up with no adding enough oil (if that is what happened), my primary concern becomes the low compression readings and what to do with only 90 miles on the Lexus Warranty.

We are a family where we put 250K to 300K miles on a car before moving on. Sadly we don't feel confident that even if we paid for the repair, what's next?

I'm failing to see the issue here. You have a warranty that is still in effect. The engine does not meet Toyota's published minimum spec. Unless Toyota can PROVE this was caused by your negligence, the warranty should prevail.

Instead of paying a bullsh_t $3000 tear down charge, pay a lawyer $100 to write a letter to this effect. Ask him to include a reference to the US Magnuson-Moss Warranty Act (1975) which covers situations such as this. Once you have brought this issue to light during the warranty period, they warranty is extended (for this issue) until it is resolved.

Wait a second.

From what I read, the low level oil warning should be on by 3 quarts low...so how did yours get 5 down?!

Yeah, I'm with 1WILLY1, keep an eye on it, and if after 1K miles, it's still at the proper level, you learned what dealer NOT to patronize!

If it's down a quart, then yeah, bring it to someone else and see what they say (but don't mention anything said, previously).

I'd drive it a while and see what happens, like others have said, the dealer could have under filled it initially. And I don't know if I'd trust their compression test reading at this point either, but if they are accurate, and you do actually have this oil consumption, it could be rings. Low compression in all the cylinders, with oil usage at 100,000 miles sounds like rings. But these cars aren't really known for that. Some people may have oil consumption but nowhere near the levels you experienced.

I'd drive it and see what happens.

FYI

Just want to update everyone. Last Monday, with only 24 miles left on the warranty AND talking with both the Service Director and Shop Foreman, we brought the car in and authorized the tear down. They both stated to me that the LS460 engine from 2007 to 2009 have a lot of parts revisions and issues.

So so far they found a leak by a transmission wire harness and also engine wire harness. They also found all the intake valves loose and for whatever reason scorching inside all the combustion chambers with one chamber really bad.

Tuesday the Extra Care Inspector comes out to review finds and go from there. Let you know what happens.

i call bs on the service manager, some 90 ls400 still dont consume a drop of oil, its a design flaw on some motors.

We are comparing different engines. Just as the 2006 LS430 was probably one of the best year/model for the LS line.

I can't, for the life of me, see how this could not be covered under the warranty(?!)

Well if there IS a way....they'll find it. "Normal wear", the part's didn't "fail", etc.That's the reasons they usually come up with. Other ways they can cut their costs is to attribute the failure of one component not covered, to be the cause of the other component failures that are covered. An example....I recall reading of one account where a warranty was denied as the failure of one component was caused by the failure of a fastener (which is not warranted). I believe that the outcome was that the warranty company made a "goodwill" offer to pay the labor but not the parts (or something like that).

Well I am well aware of the games companies and people play. We are prepared for the worse and hoping for the best.

Every time we had an engine problem an extended warranty adjuster would come out and break out his single hotplate and little pot. He would boil the thermostat to see if it would open. Every policy excludes the thermostat and they like to blame the engine failure on it and deny the claim.

*UPDATE*

Got word today with good news. Lexus Extra Care is going to repair the engine work required.
Another reason why our next car will once again be another CPO Lexus ca when that times comes.

Oh, man! That's excellent!!!

Do you get a loaner while yours is apart? I figure it'll be at least a week.
