I really want to achieve what MPG's you guys are getting, it honestly makes owning this 3GS that much more worth it! I bought my '08 GS350 RWD back in November 2021 with 93k miles, and the best that I've been able to get is 26.5 on all highway driving (refilled gas right next to freeway entrance, that's probably why) but typically 23-24 highway even if I baby the throttle, but in the city I rarely get over 19.5-20.5 and I really have to drive like a grandpa for that one.
I've tried all the common fixes, like Correct tire pressures, using "SNOW (eco) mode while driving, 3k Oil Change Intervals, fuel additives, but can never really go past these figures, no matter what I do. I think my next step is to carbon clean the engine, like @CowBoE has done on his '06 GS300 and see if it gets any better. If you guys have any other suggestions, I would very much appreciate the input.
Best, Norm

Try putting more pressure in your tires to see what MPG you get. I think I was running about 36-37. I have about 40lbs in all 4 right now. I will air back down a bit later. I was getting low pressure warnings when the cold hit where I am, so I aired up at Lowes with the intention of letting some out, but haven't yet.
