My 2011 Toyota Tundra calls for 75W85 gear oil for the rear differential. This weight is pretty hard to come by...can I use a good full synthetic 75W90? If so, is Mobil 1 a good choice?
I plan on changing the rear gear oil early because I want to squeeze as many mpg's as possible out of my truck given these high gas prices. I have heard a good quality full syntheic gear oil may help some, as well as offer really good protection long term.
Any feedback would be greatly appreciated. Thanks...
