Redline MT85 OR MT90

[dja4260]

2013 Hyundai Elantra GT, with a manual trans. The car (2-quarts capacity) currently is running MT85 (75w85). I was going to swap the fluid out as it has 40k miles on it. I accidentally purchased Redline MT90 (75w90) online and cannot return...

Any thoughts on using this fluid? Both are spec'd for hyundai vehicles in general.

My way of thinking is that it probably doesn't matter.
Will the Elantra be seeing winter duty?

Go ahead and use it.

If you cannot return it then the only way to find out if it is going to be fine in the winter is to use it. If I were you I would rather sell it and use a thinner oil because I doubt that that the thick oil will give you the same feel and the fuel consumption hit will be noticeable too.

It will be fine.

Keep the 75W90 for next summer and reorder the two quarts of MT-85.
