I've been doing the oil change on my LS460. and have not had any of the acceleration hesitation ever since..

was talking to the service advisor and he said that they also clean the throttle during the oil change, wonder if anyone knows how to clean the throttle?

Thanks,

Congratulations on side-stepping the hesitation issues. I don't clean the throttle but I do put a $10 bottle of MaxClean 20oz fuel system treatment from Royal Purple (available at Walmart) in the gas tank.

I'm raising the "serious B.S." flag on the service advisor.

texas008 - how many miles are on your car?

Ding ding ding!! Winner winner! Chicken dinner!

The service writer is a flat out liar, they are telling him they clean the throttle body to justify him going there...as if it makes them "better" or you're getting "extra". They're not doing a thing. I'd be surprised if they're even putting synthetic oil in it, or the right weight....probably why everyone is having these issues in the first place. They're probably driving out of there with 10w30 dino oil from some no name local oil company. Meanwhile they're telling you it's Mobil 1 or TGMO.

The last place in the world I'd take my car to get an oil change is the dealer.

Has anyone ever seen the room where oil is being pumped out of? Where those fancy oil dispensers are attached to? There is virtually no way for you to know what's going in your engine...even if the containers and drums say Mobil 1 or Amsoil....there are companies that will gladly pump there junk into those containers.

Pennzoil 0W-20 Full Synth at my dealer. Says so right on the service records which is all I care about. If they're pumping it full of Wesson, they'll be getting the unit back for a little (or a lot of) engine work from me or the next owner (8/125k warranty).

You are probably right. Good point and something to think about?

59k miles on the car. drives super smooth with plenty of power. I change the oil every 5000 miles using Mobile1 0w20, or toyota synthetic 0w20. haven't had any hesitation problem. it used to have hesitation problem after dealer changing the oil....

Thanks guys for all the information, will continue servicing the car myself..

I actually just finished changing my oil yesterday, as always every 5K miles with Mobil 1. I'd love to ask a Toyota engineer why they use 9 quarts in such a small engine. It's probably a good thing, but still a curiosity.

But then, I'd really like to ask why they felt the need to use that PITA oil filter when billions of cars made in the past 50 years use spin on filters with great results.

I feel the same way, I can't stand changing the filter on these cars...but they're all starting to do it now - there must be a reason for it, most likely it's saving the manufacturers money some how

From Wiki:

In the 1990s, European and Asian automakers in particular began to shift back in favor of replaceable-element filter construction, because it generates less waste with each filter change. American automakers have likewise begun to shift to replaceable-cartridge filters, and retrofit kits to convert from spin-on to cartridge-type filters are offered for popular applications.[6] Commercially available automotive oil filters vary in their design, materials, and construction details. These variables affect the efficacy, durability, and cost of the filter.[7]

If one likes to analyze their engine's performance and wear, the cartrifge style filter allows for easier inspection of contaminants. Also, the cartridge filter allows for the engine to use it's own system of oil byass valves and that sort of thing and less oil starvation at startup. There are more and more cars coming out now that use this system and many retrofit systems are available to change to the replaceable element system. Heck, I think even the Chevy Cruze now uses it. I just wish that the housing were located on the top f the engine under the hood like my wife's BMW X5!

just finished mine- mobil 1 0w20 with oem filter took about half an hour- pretty easy job.

roadfrog

It really is an easy job. Easier than some spin-on filters I've had to be a contortionist to reach.

What I might do is buy one of those aluminum housings, like Devh suggested. Might make my life a little easier, the plastic one I have is a little messed up.
