THIS DIFFERENTIAL FLUID KIT BLAUPARTS…

THIS DIFFERENTIAL FLUID KIT BLAUPARTS IS SELING TO TOYOTA TUNDRA OWNERS FOR FLUID CHANGE IS THE WRONG FLUID. ON THE BOTTLE, READ WHAT'S WRITTEN IN THE RED LINE ABOVE THE 85. IT'S TRANSMISSION FLUID. THAT IS NOT WHAT IS SUPPOSED TO GO IN TOYOTA TUNDRA DIFFERENTIALS. THE TUNDRA OWNERS MANUAL SPECIFICALLY STATES "TOYOTA GENUINE DIFFERENTIAL GEAR OIL OR AN EQUIVALENT OIL OF MATCHING QUALITY. TRANSMISSION FLUID IS NOT AN EQUIVALENT OIL FOR GEAR OIL.

Response from BlaupartsAug 11, 2021

Hi Tom, we’re sorry to hear you were not satisfied with the product you received. We apologize for any confusion caused by the labelling on the bottle! As we mentioned in our email replies to you previously, the RAVENOL MTF-1 75W-85 Gear Oil is a direct replacement for Toyota gear oil part numbers 08885-02606, 08885-81070, 08885-81060 (equivalent to the 08885-02506 U.S. part number). We have a blog article dedicated to discussing this frequently asked question about the labeling here: https://www.blauparts.com/blog/why-mtf-is-recommended-for-some-toyota-differentials.html You will also find that on the manufacturer's website—www.ravenol.de—the RAVENOL MTF-1 SAE 75W-85 product is listed as suitable “for special manual transmissions, transfer cases and differential gears.” In addition to this, you can find numerous positive reviews and testimonials accumulated over several years from Tundra owners like yourself that are successfully using RAVENOL MTF-1 SAE 75W-85 in their differentials on Amazon, our website, and various Toyota forums. However, if you do not want to use the RAVENOL MTF-1 SAE 75W-85 that meets Toyota gear oil part numbers 08885-02606, 08885-81070, and 08885-81060 you are more than welcome to return the product for a refund by visiting blauparts.com/returns. Again, we sincerely apologize for any confusion caused by the labeling and know we are actively working to have RAVENOL Germany update the labeling on the bottle to reflect more clearly the full application range of the product.
