    • Lubegard Gear Supplement
Size: 8 oz.
Another update May 2023: I've since used this in so many different vehicles not just by own but families and friends. It has helped on a couple of occasions quiet down a noisy diff, not completely but definitely quieter. And no chattering or noises from any of the Ford differentials I've put it in. Over several years of testing I can honestly say great product! Not sure if I would use it in a highly sensitive manual transmission though as it does reduce friction quite a bit which is a great thing but sometimes not so much in a manual transmission :) Update October 2018: The benefits i had noticed continued in the F250 while i had it (no longer have it) and also used it in a new application: a 2016 Ram 1500. I chose to use Redline 75w140 and this product as directed. The axle performed as i expected; very quiet. There is also LG in the motor and this truck runs beautifully. Average mpg over 24,000 miles is 19.9 combined. Not bad for a Hemi! I've used this product in my Ford F-250 in two different applications; the 4spd manual transmission and the rear axle. Using this product mixed with 80w90 in the manual trans made a considerable difference in shift quality, especially when cold. I also added a bottle in the Dana 70 rear axle w/ limited slip. Used Valvoline 75w140(contains friction modifier) and one bottle of Gear supplment. No problems after 500 miles and the axle is whisper quiet, no chattering. Lubegard isn't the sole reason the axle is quiet, but in my opinion a contributor. The LXE technology Lubegard uses has an amazing effect on reducing friction. I've used Lubegard's products in the engine, auto and manual trans, axles, coolant, and power steering with success in every application. Use this product with confidence. ... show more

    • Amazing additive for petroleum based gear oils
Size: 8 oz.
This product improves petroleum based gear oils giving them performance similar to synthetic variants. I love Lubegards products and have used many throughout the years. My only advice is to buy this at NAPA because it’s $9.99 there not $19 + which is a total rip off!

    • Lube Guard is an old company with a very good reputation
I purchased this on Lube Guards reputation; I have used the automatic transmission additives for many years from LG - and with very good results; so, I am running a trial on this; the results in a manual gearbox (Miata) with many miles on each (I have two Miatas) are subjective to some degree - but I am running this additive primarily as a protectant and not expecting observable behaviour such as shifting; I have LG in the differentials now too, so again, just looking to protect and prolong the life of the unit; the technology that LG claims is called LXE. So you can read more about that on their website; ... show more

    • Well it was worst than with the old oil
Size: 8 oz.
This "snake oil" as most would call it, helped me when it was added to a 6 years old 75w90 subaru manual transmission oil. After a month I poured some not very popular or expensive gear oil- 75w90 fully synthetic by the Belgian company "Wolfoil". Well it was worst than with the old oil, so I remembered Lubegard yellow bottle helped me once and purchased again. As expected even with only one bottle(recommended is two bottles for 4-5lt. of oil) and after just 2-4 km. of driving and often shifting, the gears were shiftables as never before just like a new car. I am the third owner an the first registration was in1999 ☺. Amasing additive indeed ... show more

    • Worked great for five speed manual transmission
Size: 8 oz.
After draining and refilling my five speed manual transmission twice with Lucas 80w-90 over a three week period, the transmission was still a little rough and did not slip into gear as it should have. After adding lubegard gear fluid supplement and driving around for thirty minutes or so, the transmission felt like someone had just rebuilt it, amazing! ... show more

    • Made my Sentra shift worse - too slippery for proper synchro functioning?
Size: 8 oz.
This product immediately made the manual transmission in my Nissan Sentra shift much worse. I can barely get it into first gear when standing still. My feeling is that the increased lubricity makes the synchro's less able to grab and equalize the shaft speeds. I really like Lubegard products for automatic transmissions, and this stuff is probably great for rear-ends, but it was not helpful for my application. ... show more

    • Works great in my NV5600
Size: 8 oz.
I've used this in every fluid change in my 2001 Ram diesel 6 speed NV5600 manual trans. Makes the shifts butter smooth. Remember - always match the engine speed to the drive line speed on down shifts by "blipping" the throttle. Makes for easy as pie down shifts every time.
