The 15W-50...20W-50...Straight 40 and 50 all look good as far as the base numbers go compared to premium synthetics...got any ZDDP levels and detergent numbers for me?
What brand is it?

Re: Marine Lubrication
Hydro,thats the "sentinel synthetic" I was asking you about a few months ago. I have never had it tested, I spoke to the engineer in florida that works there and he wouldn't tell me the zddp # but said its pretty high? They put "virgin" molybendmeum in it as a low friction additive. We tested a circle track motor that made 250 hp at the tires and around 350 ft lbs tq a few years ago on a chassis dyno and saw a 17 ft lb tq increase at peak and smaller gains up and down the peak so it must be slippery.I have also seen a few street cars that ran 14 or 15 second 1/4 mile times that picked up a tenth in 1/4 mile. I sell alot of it to local circle track guys but quit trying to sell it to everyone else because they won't pay the extra 5$ a qt over dino oil. I am curious what your take is on it,like I said earlier I run it in all my own stuff (except boat blower motor)and have been for almost 15 years. I don't run it in boat because I change it every 10-12 hours and just won't spend the coin for 18 qts of oil every 2 weeks. I can send you a qt if you want to get some tested,I'd even pay for the testing to see how it actually stacks up against the big name stuff,Smitty

Have you ever done a 30-50 hour tear-down inspection?
What do the main bearings look like?

I originally tried the stuff because I had built a jet boat motor with aluminum rods and ended up with BIG oil clearences and they have a 5w/60 wt that carried good oil pressure in that application.I became a dealer with a nominal buy in where I get 30% off their list price and free shipping/handling which puts it just under 6$ a qt in 24 qt cases,cheaper yet in 6 gallon pails. The stuff is real grey looking out of the bottle and messy/clingy,you have to let a motor sit for a while after running it to get a accurate dipstick reading. Keep up your good oil info,Smitty
