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?

Comments about Mobil1 Synthetic Gear Lubricant LS 75W-90 (1 qt.):
Mobil1 Synthetic Gear Lubricant LS 75W-90 (1 qt.) offers superior differential gear and transmission lubrication. I had my 1998 Toyota E153 manual transmission completely rebuilt 75,000 miles ago and I've used Mobil1 Synthetic Gear Lubricant LS 75W-90 gear oil ever since. Happiness is having silky smooth shifting and the occasional power shifting street induced incidences without experiencing any transmission issues or problems.

Comments about Mobil1 Synthetic Gear Lubricant LS 75W-90 (1 qt.):
You would have to buy a friction modifier to use it in a limited slip differential. Royal Purple is far more expensive but at least you don't have to go to a dealer to get the modifier.

Comments about Mobil1 Synthetic Gear Lubricant LS 75W-90 (1 qt.):
This product is the world second best. This oil can be used not only in limited slip but also in conventional differentials. Exxon Mobil don't make non-LS Mobil 1 gear oil any more because this can replace them.
What is the world best product? Mobil Delvac 75W90 is the best. It has higher flash point than Mobil 1 LS 75W90. I hope advance auto parts stock the product.

Comments about Mobil1 Synthetic Gear Lubricant LS 75W-90 (1 qt.):
Product was easy to use. Was used on a Silverado pickup differential maintenance. If the bottle design was changed a little to allow for the last quarter amount to be added, it would help in the installation. But overall, it was a breeze.

Q:
I have a 2003 Sentra Spec-V. The Nissan service manual specifies 75W-85 GL-4 oil in the transmission. I have read elsewhere that GL-5 oils can potentially be harmful to the transmission if the manufacturer doesn't specify it for a GL-5 oil, but GL-4 seems to be possible to find on your site anywhere near the required viscosity. Will this product work in my vehicle, and if not, what will?Asked on 10/30/2012 by JBeams1 answer
CUSTOMER CARE
A:
Sorry, this Mobil1 Synthetic Gear Lubricant LS 75W-90 (1 qt.) - part# 98W573 is not compatible for your 2003 Nissan Sentra Spec-V. Right now we are unable to locate the exact gear lubricant with API GL-4 specification for your vehicle online. However, if you could please visit your nearest Advance Auto store or call us directly at 1-877-ADVANCE (238-2623) one of our representatives there would be more than happy to assist you.Answered on 10/31/2012 by Vincent from AAP
Q:
can I use this in my drive shaft gear box of a 2006 yamaha 650 vstar and whats the different s between GL-4 and GL-5Asked on 8/21/2012 by none from orlando fl1 answer
CUSTOMER CARE
A:
Sorry, this Mobil1 Synthetic Gear Lubricant LS 75W-90 (1 qt.) - part# 98W573 is not compatible with your 2006 Yamaha V-Star 650. GL-4 and GL-5 are standards set by the American Petroleum Institute for gear oils. GL-4 are intended for axles with spiral bevel and hypoid gears operating under moderate to severe conditions of speeds and loads. They are also suitable for sychronized manual transmissions when MT-1 gear oils are NOT recommended. GL-4 should be used in limited-slip differentials. The GL-4 generally indicates "Limited Slip" properties in the gear oil. GL-5 is indicated for high-speed/shock loads and low-speed/high-torque conditions. GL-5 also has multi-purpose or mild EP (extreme) properties too. GL-5 is often seen with the MT-1 designation too. For any further assistance, please visit your nearest Advance Auto store or call us directly at 1-877-ADVANCE (238-2623) and one of our representatives there would be more than happy to assist you.Answered on 8/22/2012 by Vincent from AAP

Q:
What does the W stand for and is it important?Asked on 7/20/2011 by ray from campbell, ca3 answers
A:
Multi weight lubricants have special additives that change the viscosity with temperature. 75W-90 means it acts like a 75 weight (relatively thinner) oil in cold climates which allows less cold operation friction and resistance to flow. As the oil warms up the additive package acts to prevent the normal thinning process, hence it acts like a true 90 weight oil when hot. Straight 90W gear oil is quite thick during cold weather, which not only causes increased drag but also it resists flow so it doesn't lubricate as well. So the W is very important.A:
The W is for WeightAnswered on 3/3/2012 by Eagle from Cut & Shoot TexasCUSTOMER CARE
A:
It represents the grade of the oil.Answered on 7/21/2011 by Steve from AAP

Q:
Can Mobil 1 LS75w-90 be used as a gear lube in a 2001 Harley FLH transmission?Asked on 4/18/2011 by Rider from Pandora, OH1 answer
A:
I worked for 2 H-D dealers over a 6 year period. It is too thick for your Harley Davidson transmission. Stick with H-D Tranmission Fluid or H-D Synthetic Fluid. They work the best. Do not use gear oil.Answered on 5/17/2011 by Road from New Jersey
