even if it was tested it will come back as the right viscosity.
now their transmission fluid... it has a marker chemical in it.. and your transmission fluid needs to have it or they get real ..um shiesty with their warranty at that point usually.
If you're still using the same trans fluid that Hyundai recommends that you use, why should they give a [censored]? The trans flush at the dealership is $140 or some crazy stupid high number. I can do it myself for $60 (valvoline ATF) and the valvoline has a higher temperature resistance and meets Hyundai's requirements. Hyundai has very dumb rules on what you can and can not do.
Valvoline isnt a manufacturer approved transmission fluid its a "meets or exceeds SPIII" fluid
It wasnt certified by hyundai or anything.
The manufacturer Claims it meets or exceeds the SPIII spec.
also by your logic you could do the flush with the hyundai fluid for 10$ more than the valvoline fluid.
You can also use mitsubishi or kia spIII they are all identical (sometimes one or the other is cheaper)
IMO both(valvoline and geniune spIII)are fine but if I had a warranty I'd use the 6$/qt fluid from the dealer. They get REAL shiesty esp once you are in the 10/100 warranty and out of the 5/60 bumper to bumper.
52k on the clock and 3 year old car.
10/100k warranty is in place.
I track the car, the Hyundai fluid that I used went from red to black in 2 track events, i've had valvoline in for the past 7 events and it's still bright red.
Did a little research before going with Valvoline, it's better than Hyundai's SPIII in almost every way, it's easier to get, comes in jugs instead of $100 14 quart tubs, and multiple people have had good luck with it. Plus.. there is an 11 second tib putting 420 to the wheels that was running Valvoline ATF, and it's a stock trans.
Mobis makes amazing parts for Hyundai. I trust OEM (Mobis) over any other brand out there for regular maintenance/replacement (timing belt, gaskets, etc.), but as far as fluids go.. i'd rather get something tried and true than something that is "certified" or "recommended" by Hyundai.
It won't void your warranty, because they can't simply blame the fluid that you used. They have to PROVE that the fluid that you used caused the failure that it did, and there isn't a single case where using the non-Hyundai recommended fluid caused a failure that was fluid related.
I'll stick to what works best, not what is approved.
