This model has a "sealed" transmission, so no dipstick. Drain plug, overflow plug, and fill plug. I've done the radiator line method on other cars, but I leaned slightly toward the drain and fill being easier with the sealed trans. Radiator line probably would have been easier, honestly. But...

I just drained the ATF for the 4th time and the fluid is still dirty. Cleaner than the last time, but still significantly darker than the new red stuff. (Using Valvoline Maxlife Synthetic.) Is this normal for this trans? The car has 125k miles on it, and this is probably the first time the ATF...

I've got the 9mm and I love it.

Same here. Like I said in the first post, I've generally done this along with multiple other maintenance items. But a small increase in MPGs is common. I do the oxygen sensors preventatively because it's easier to plan the maintenance and do everything at once than it is to respond to a...

Over the years I've replaced many o2 sensors in many cars. Often I'll replace the upstream sensors around the 100k-150k mile range as a maintenance item. The upstream replacement--typically done around the time of other items such as trans flush, ECT replacement, filters, spark plugs, etc--often...

Originally Posted by Villalobos I like GTMO and Toyota filters for oil change in my IS. I know nothing at all about the Toyota oil, but aren't people not very happy with the Toyota filters? I've read a bunch of stuff saying they're not very good for the price. But I'd imagine this is one of...

Update: I just did my second oil change. Went 9,120 miles on Pennzoil Platinum HM 5w30 and a Mobil 1 201 filter. Changed with the same oil, and the larger M1-209 filter. I'm planning for 7,500 miles this time. I'd meant to go 8k on this change, and accidentally let it go longer than I'd...

First oil change today, at 8k on the Lexus (Toyota) factory synthetic. I ended up going with Pennzoil Platinum High Mileage 5w30, and a Mobil 1 filter. Both on sale at Walmart. I'm probably going to stick with 8k changes. My turbo cars often went around 6-7k on Rotella T6, M1TDT etc, so I feel...

I just bought this car. It has 110k miles on it. It's currently in with an independent mechanic getting the timing belt and water pump etc done. (I wish I could have done it--I just don't have the time or tools/space at the moment.) I need recommendations for oil--20k miles per year...

Thanks again to everyone who responded. But, in the end, I didn't buy the GX. I was just about to and prepping for what I'd need to do when the PPI revealed a bunch of problems. I did end up buying a 2006 LS430. So I'll make a new thread about that one. Sorry to everyone who took the time to...

Thanks, everyone! This was a ton of very good info. I haven't purchased this car yet, but I'm going to if tomorrow's PPI goes well. If 5w30 is the recommended oil, would a thin 40 be okay? I've had euro cars up to now, and have almost always used one of four oils: M1TDT 5w40, Rotella T6 5w40...

I'm looking for a good year round oil that can do ~10k miles. I don't care about the price--just whatever can handle those miles the best. Mostly highway driving, no short trips. Northeastern climate, so something that can handle cold starts below freezing. ~20k miles per year. The engine...

I'm changing the oil in my sister's car, and it was on sale at Walmart. Any reason not to use this oil in this car? She's likely to leave it in there for quite a long time, probably 10k+ miles, so I wanted something that could handle it.
