I have read threads in the IS F forum and the RC F forum related to owners getting more oil than they bargained for with Lexus service. I was quite dismayed to see the oil level almost a full two inches above the second dot on the dipstick when I checked it. We drove the car on a 7 hour road trip (each way) this last weekend and the gas mileage was really crappy (23mpg vs. 27 mpg) compared to the IS, which I did not expect at all. I figured I'd better check the basics, and sure enough - big time overfill on the oil.
I normally do all maintenance myself, but since this one was included in the purchase price, I figured I'd let them do it. Sad to say I drained out almost 3 US quarts to get the level where it should be. It would seem the tech looked at the dry fill number, not the oil change number in the factory service manual and put in 11.4 US quarts when it should have been 9.3 US quarts - plus a little extra (or maybe the drain wasn't a full drain).
In any case, it only reinforces my concern about letting someone else do something which should be simple, and having it not done right. I used a vacuum pump, 2 quart jar, and a 3/16" hard plastic tube to remove the excess oil. I cut the tube to the same height as the top dot on the dipstick and installed it. I just didn't expect I would need to empty my container twice to complete the job. Very frustrating.

Thanks for the heads up, while i don't own a GSF, I have a free oil change in 2000 miles so i will make sure to check oil level before leaving service dept.

what mode do you drive in? I can't even get 23 mpg!

Road trip mode. Fill up with gas, get in the car, drive until empty at freeway speeds. You should see at least 26 mpg doing this. I have seen as much as 28 mpg in my IS F doing this on multiple road trips. Eco, normal, sport, and sport plus don't really impact your fuel mileage. Your right foot impacts it dramatically.

Thanks for the head's up Lance and I will have to go out and check my oil level. I also agree with you on your highway mileage for both the ISF and GSF but as far as city driving in the GSF, for me I am barely breaking 16 mpg and that is 90% non-spirited driving (only because too much damn traffic in ATL). That said, did not buy this one for the fantastic mpgs...
I will let you know if Lexus service got me too since I got the complimentary 5K service about the same time as you all did. Fingers crossed.
so prior to purchasing my car, i had my dealer change my oil since the car was sitting for a few months on the lot. Decided to check my oil level ths morning and i noticed the oil level was above the second dot dipstick not by much but by a noticeable amount. Now my question to the experts is, what the heck do i do now. with almost 2000 miles on the car, how much damage could I have possibly caused. Or should i let the engine warmup first and then check the dipstick.
My father always told me you need to check the dipstick when the engine is cold to get a "true" reading... hopefully you guys can help me out. Thanks

Lexus indicate let engine warm up and wait 15min to check the level
take to the dealer, they have a tool to suck it out
Thanks!! ill have to take my car in next week then. This may explain why I'm getting roughly 15mpg city and highway combined... lol when I'm doing just local driving I'm getting 12 mpg..
I consistently get 50 miles per quarter tank so 200 miles per tank. Is this consistent with what everyone else is getting? I know this car wasn't meant to have good gas mileage btw lol

Was it a true 5k service? By that I mean does your car have 5k miles on it? The reason that I ask is because I think a true 5k service is basically an inspection service. The oil isn't changed until 10k. We have a 2015 GS350 F-Sport and that's how it is on it. Not so sure on a GSF though.

I just had my oil changed on my GSF yesterday and this morning when i went to check the oil level with the car off, cold, on a level surface and the reading showed above the second dot fill line by about an inch...
i turned the car on, let it idle, then turned it off and waited 5 minutes per the GSF manual (p401). I then rechecked the dipstick and it was showing at the correct level. Not sure why a regular cold check would not show the same but at least it checks out at the correct level
So i went to check my oil level again since it just seemed weird to me that the oil level would be more accurate the way the manual describes to check it...
so i waited overnight and decided to check my oil level again and heres what I found
Filled way above the second dot fill line!!
It was filled WAY above the top full dot! So I had the oil sucked out from the dipstick and took out about 1.5 quarts to bring it back to the correct level.
so goes to show that even at the dealer they overfill.
Always make sure to check your level after you have your car serviced no matter where you take it!

read post number 8 and confirm it with the owners manual
Overfilled oil on 5k service
Also on level ground.
