Changed to Mobil LS1 in my 2006 Tundra 4WD Limited slip (LS) about 8 months ago. After about 3-5k miles I started getting a chattering noise when turning sharp. Thought it was the front end, could not find anything wrong. Transmission maybe??? So I had the trans flushed at the Toyo dealer.(120k miles on truck). Could not be my rearend...I have Mobil 1. Changed over to Lucus 80W-90 standard gear oil with 1/3 of a bottle of the KW LS additive. My truck drives perfect again and turns are very smooth. Can't believe it took me 20k miles to figure out this product is all hype. The oil was still very clear though when I drained it. Only positive thing I can think of?

            Synthetics are always the best lubricant. Shear strength, viscosity consistency and ease of use in any climate are always benefits of synthetics over conventional petroleum products. I use Mobil 1 products in my GT, my H-D, the wife's Lexus and my 17 year old 4Runner. Good stuff.

                A:

                Hi Strahil, I'm glad to assist you! Unless the transmission specifically recommends an API GL-5 fluid for your transmission, it should not be used. GL-5 gear oils are designed for gears that require a high level of EP (Extreme Pressure) additives to protect gear teeth under extreme stress. Regrettably, these same additives can be very aggressive toward "yellow metals "and are generally not recommended where copper, brass and bronze components are used.

              Asked on 9/20/2015 by Rod from Lakeway, TX.

              • CUSTOMER CARE

                A:

                Yes, Rod. You can use 75W-90 gear oil instead of 80W-90, unless your truck specifically says not to run 75w-90 lube. If you have a limited slip differential, you also need to add some LS fluid. However, we do offer the Valvoline High-Performance 80W-90 Gear Oil (Part No. VV831) which has the API Grade Rating: GL5 or MT-1.
