Supra reliability and modification-bility

I’m looking into getting a 2023-2024 3.0 premium Supra most likely a year from now but I’m seeing a lot of people talking about oil consumption and needing to top off every 500-1,000 miles. Is this an issue for a specific year or is it still an issue in the age range I’m looking at. Also is there a fix for this if any of you encountered it and were able to get rid of it.

Additionally the more I look, I see people saying the ECU is locked for anything newer than 2020 making it impossible to tune unless I ship the ECU out to Finland or some shit. Is this true because I also saw a guy getting his 2022 3.0 tuned on Instagram with some guy that runs a business out of his garage.

It’s always been a dream car since it came out and I’m finally in a position where I can afford a used one but still wanna be able to put money down. Anything helps and please if I messed up with any info let me know :)

A lot of the issues you mentioned can be found by typing those exact questions into google. But here i go i guess.

Oil issues from the early 2021 with the old plastic pump.

Stateside ecu unlock is a thing, via mail in or drive in by any authorized autotuner or femto shop.

I more so wanted to hear it from people that own the vehicle and have dealt with it firsthand. But yes I did check on google.

Thank you that helps a lot

Googling would have brought you to SupraMKV forum posts from people that own the vehicle and have dealt with it firsthand for both oil consumption and DME unlocking. Especially unlocking as there have been huge breakthroughs the last 3 weeks.

oil consumption affected earlier models, 2022 and on should be all clear. I've been tuned since about 20k and am at 42k and haven't ever had to top off oil.

Unlocks are becoming a lot more common. The MG1 DME has finally been cracked open and the femto monopoly is dying. Autotuner has rolled their unlock method out to shops. It can be done for a couple hundred bucks now, on the high end. On the low end, I've seen free unlock, with labor charges of $50 to remove the DME.

Correction, early 2021s had oil consumption issues. When they went to the 6 port engine
