Re: Marine Lubrication
Curiosity got the best of me. I have had a tractor with a 16HP Briggs Commercial V-twin engine running for 921 hours over the last 14 years. I had been using Mobil-1 15W-50 for 12 years and for the last 2 years Mobil-1 20W-50 V-Twin.
I ran the tractor for 21 hours over 2 months in 95*F heat and sent in a sample to Blackstone.
The report is kind of hard to read..here is what it says...
Report: Mobil-1 20W-50 V-Twin 21 Hours Service:
"Since this oil is still in place we suggest leaving it there for the rest of the season, and then resampling when you change it out for winter. 50-hours is the average oil use for this type engine, and the hours on which universal average wear is based. We have a feeling from the near-nonexistant wear levels, that you may be able to run far longer than 50 hours. Lead (3 ppm), from the bearings, was there, but nearly nothing else. Iron from the lined cylinders was only 1 ppm. The TBN of the oil was 9.7, so you have hardly touched the active additive in 21-hours of use. No harmful contaminants were found in this sample".

Re: Marine Lubrication
I was asked if I did a 30 wt analysis.
I never used 30wt personally...but..
My neighbor bought the same tractor and engine 14 years ago. He used B & S 30wt. His tractor engine lasted 9 years and had 750 hours on it. He had it rebuilt and now uses M-1 V-Twin.
My tractor engine has 921 hours on it and runs like new.

Re: Marine Lubrication
For those of you that use Mobil Synthetic gear lubricants in your boats and personal vehicles, there will be a name change hitting the streets.
- Mobilube SHC 75w90 will be soon called: Mobil Delvac Synthetic Gear Oil 75W-90
- Mobilube SHC 80w140 will soon be called: Mobil Delvac Synthetic Gear Oil 80w140
- Mobiltrans SHC 50 will soon be: Mobil Delvac Synthetic Transmission Fluid 50
Quote from XOM
"or about October 1, 2005, we will begin selectively migrating our drivetrain fluids towards the "Mobil Delvac" franchise umbrella with the goal of creating more meaningful product names. The migration will be implemented in a phased approach with the first phase impacting select synthetic (flagship) power train products. Future phases and their impacts on products and timing will be communicated at later date. "
"Timing & Availability ---------------------------------------------------------------------------------------
. As stated above, implementation will be on or about October 1, 2005.
. This will be a running change and there will be no impact to current product availabilities.
. Sourcing, package sizes and pricing remains the same as today.
. There will be NO IMPACT on product formulation, performance or claims.
. Material codes will change and the new codes will be communicated on or about September 1, 2005. "

BTW....with the V-Twin 20-50 my oil pressure stayed about the same as it was with the Valvoline 20-50 synthetic.
Oil temp DROPPED about 10 degrees.
Thank you gentlemen

Re: Marine Lubrication
That's not too bad of a deal.. Some will be cheaper some will be more expensive. I just dump my price to be kind to the local OSOers! Glad to hear it worked.

V-Twin M-1 is the best oil I have ever used. I use it in everything I can. If I need a lower viscoisty I use the 10W-40 M-1 motorcycle oil. Dosen't get any better. Period.

The price dump is appreciated. I was going to pm you about getting the VT from you. But seeing that I get oil in a small quantity {single BB and maybe about 35-40 hrs. per season} I did'nt think it would be worth the effort on your end.
What's the word on the V-Twin 10-40? I know a guy that is looking for the benefits of the V Twin 20-50, but in a lower viscosity. His oil pressure is on the high side, so he does'nt want to go with 20-50. Would the V Twin 10-40 be a good substitute? And would it help with oil temps as the 20-50 does?
Thanks

Re: Marine Lubrication
Hydro - That is good news about the bearing temp possibly being so much lower.
Another thing I was concerned about were seals in the engine. I was told that getting over 240* could cause damage there.
