Running Mystic JT7 85W-140, Yes Mystic, in Mercury BlackHawks with 1:50 Gears attached to 550 Horse on each. Inexpensive enough to change a couple of times a season to check for any metals in the oil. Comes out a Pretty clear Red each time changed over the past few years. Was turned on to it by the late Brad Smith, SMITH POWER and will never change.

This got me thinking as i need to fill both drives and will probably change the fluids in my Duramax also seeing how I'll be trailering this season. Just found a local shop that has the Mobil 75-80 in quarts for the normal $12 and 75-140 in 5 gal pail for $180. Do you think there would be an added benefit to running the 75-140 in this situation?

Not sure why anyone would be surprised by results using MYSTIC? Very high quality lubricant company. I use their greases exclusively. Thanks for sharing! Brad was a bright guy and left a void when he passed, however his legacy will live on forever and keep this sport we all cherish going strong for years to come.

I just used the Severe Gear 75w140 and it has a nice aroma. It has to be good.
Joking aside, I did just put it in. I also bought the Severe Gear 190 and I might even try it in a few weeks. It is a cool electric green color. If 140 is good, 190 has to be better right?

yep Mystik motor oil and gear oil, been using in the shop for over 2 years now, not a problem and worth the price as so far.about 400 boats have it without any problems that I have changed. O'Reillys just had a 8 qt / jug on sale for 24.99 for the motor oil15 - 40. I think something of Citgo oil is in Mystik oil products. No 100 % sure but do I know merc motor oils are made by Citgo and the merc premium gear oil is made by Citgo as well.
