OK, I see that for the 2010 model year, the LS has gone to 10,000 oil changes. I am wondering, OTHER than for warranty reasons (which I admit is a BIG reason), is there any reason for 2009 (or 8 or 7) owners to not also adopt 10,000 synthetic oil changes???

Put another way, is there any engineering difference between the 2010 engine and the 2007-9 engines that would make the the 07,08 & 09 engines more likely to have problems by going to 10,000 miles between changes.

I have 1991 LS 400 and have been changing my oil at 10,000 miles since 1993 and the car now has 237,000 miles my 1986 Toyota Cressida went 529,000 miles on mobile one and no problems also had snythetic trans fluid in both cars and no problems I now use the new mobil one extended and chance my oil at 15,000 miles my lexus averages 100-300 miles a day as a sales car MB BMW Corvett Porche, Audi and 10 high end cars have been using synthetic oil for the last 10 years and go 10,000 miles between oil changes figure that.

Seems like the BIG secret car makers dnt tell the consumers. I find it funny you say you wait 10,000 miles. I wouldnt be surprised if with synthetic that would save money for car owners as well. I do 5,000 miles myself but, always wondered if I needed to just to maintain the car. Oh, well at least I know some new info!!! Great info!!! These are the times I truly enjoy clublexus! Great info!!!.L.G.N.M

No one really answered my original question: Is there anything really different between the '09 and '10 engines?

cmasten

I am not aware of any differences between 07-10 engines

So now I'm hearing the new 2010 RX and LS460 have 10K oil change intervals.

None. Everything is a carryover.

My new GX 460 also says every 10,000 miles, or once a year. I'm going to stick to every 5,000 miles, or once a year using full synthetic oil.

I am using Eneos oil and I change it every 5k mi regardless.

I don't play cheap when dealing with my cars.

BMW MB and all high end Europen cars are now using synthetic oil of different kinds or brands and going 10k between oil changes LEXUS JUST STARTED USING SYNTHETIC OIL I HAVE BEEN USING IT SINCE 1986 AND HAS A CRESSIDA GO 529,000 AND NO PROBLEMS my 1990 LS 400 has just about a quarter million miles with mobil 1 and everything is still perfect I use it in all parts of the car PS trans motor and rearend....

So when are the Lexus service departments going to quite giving us BS and just advise using the same synthetic oil as factory filled in the new RX350, GX460, etc.

The last time I went to the dealer the SA advised against it, with a lame excuse about the inspections every 5K miles, and this was a fairly experienced SA. I wasn't impressed.

Interesting information. My dealer uses a synthetic oil in my LS but I still change it every 5K which is about every 6-8 months for me. Interestingly at 5K the oil still looks pretty clean.

Any car recomended 10K oil change are using Syn oil AND longer lasting oil filter, only Synthetic oil is not enough unless you can find a filter for your car can last 10K+

I just had mine changed at Toyota yesterday and they used a synthetic for the first time- at least according to my records, they used "Guaranteed Lexus Oil" for the first 25K and we changed it every 5000 miles. Yesterday the bill was double (usually about $ 48 and it was $ 90) and the shop ticket said synthetic oil was used. I called the service rep and he said that the current recommended oil for the car is synthetic. I asked him then if this measn that we can go 10000k like the 2010 now recommends and that through him a curveball. He said he hadnt heard that, but would think I sould be able to go that long.

The previous comment about the filter is an interesting one, but I assume the filter is only as good as the oil. If the oil isnt breaking down and getting nasty, then the filter doesnt work as hard. Whats everyones thought about the filter going 10K or have they redesigned the Lexus filter to be able to also go 10K.

And lastly, if they are switching the recommendation for the oil, will there be a software upgrade to change the cars setting to not trigger the 5000 mile change and go to a 10K change.
