The OEM fluid is 75w85, API GL4. It states in the owners manual that fluid meeting this specification may be used, and won't void the warranty. Keep your reciept to prove it was changed.Use OEM stuff to preserve the warranty.
Good point! Same reason manufacturers can't force you to service your vehicle with them, monopoly!The OEM fluid is 75w85, API GL4. It states in the owners manual that fluid meeting this specification may be used, and won't void the warranty. Keep your reciept to prove it was changed.
A manufacture can only force you to use their fluids if they are provided to you at no charge or the fluid is "lifetime" no service required, they cannot force you to purchase it.....otherwise this would be a monopoly, and they could charge you $1,000,000/liter, and you would have no choice but to buy it.
If the manufacture denies a warranty repair, and claims it is the fluid that caused it, then it is up to Hyundai to prove that the "other" fluid manufacture is making an inferior product, and therefor caused the damage. Then sit back and watch the slander, lieble, and wrongful accusations fly from the "other" manufacture. As long as the fluid specifications meet the OEM requirement (75w85 API GL4) then use with confidence.
I plan on using Redline 75w85 in mine this year when it is changed
I don't know how they compare but I'm sure they beat the cheap OEM stuff.Hey guys thanks for the nice reception! I plan(plan mind you) of doing some modifications on my car. Is this redline superior to the royal purple brand or do they both meet the requirements? And I assume I just have to drain the old fluid and put in the new correct?
I heard it in HYUNDAI Manual Transmission Class at training facility from instructor' mouth...I have read that it has something to do with the brass rings used in the transmission that the GL5 additives do a number on.
100% correctI heard it in HYUNDAI Manual Transmission Class at training facility from instructor' mouth...
GL5 has sulphur content that will destroy the brass synchro rings.
I have a co-worker that insist on using the Hyundai bottled 75-90 which is GL-5 is correct oil per old bulletin showing change of part number for the GL4 oil ,,, he has not put it together that the stuff he is using is wrong, even via part number on bottle and bulletin, as Hyundai used to use 75-90 GL-4 until they stop and went 75/85.. he just see the 75-90 description.. I'm not arguing it with him any more.. so if you have M/T work or clutch done at dealer, inspect your invoice' parts list and make sure the 75/85 GL4 oil was used for refill.
