Re: Marine Lubrication
 

How lubricants affect fuel economy (they used diesel engines but the data is similiar in gas engines they tell me)...the oil information battle goes on... :D

...in a nutshell the data shows that "engine bearing friction" robs the greatest about of horsepower and with the right oil and additives can "give some back too". It then makes sense that oil related engine failures would show excessive bearing wear or damage.

Got prematurely worn bearings...?? solution..Premium Synthetic Oil.

Mobil Delvac 1 can show a 3-6% fuel economy boost... Also you can extend your drains thru the Signum Oil Analysis. There will also be a 1.8 million mile testimonial available on the market soon.

We have a customer who goes thru 1,000,000 gallons of fuel a year. 6% is a big number for them to save on gas. As well as the labor costs of extended drain intervals.

What does anyone think of the Fram ToughGuard TG30 filter used with VTwin 20W-50 synthetic on a 1996 502 Mag with 135hrs?

Thanks

Enough All Ready. We've Been Through Every Oil And Oil Filter Ever Made 10+ Times.

Re: Marine Lubrication
 

The Fram Tough Guard is one of their better filters and is considered genarally a middle tier filter.

An Amsoil SD...Mobil-1...would trap better and flow as good as the Tough Guard...if you want more flow and a bit less filtering then the k&N impresses me in those respects.

Re: Marine Lubrication
 

I realize we have "been there and done this" the info is in the early pages of this thread...but he asked.. :D

I always try to bring new info to the table and do not mind if in the process we stop for a question from the past...

...nothing has really changed in oil filter land...

To recap:

Max filtering/max flow:
Amsoil SD

Max filtering/ good flow:
Mobil-1/Purolator Plus

Good filtering and flow and "cheap price":
A/C and Fram Tough Guard

Good trapping/Excellent flow:
K&N/Wix Racing/Mercury HP/Baldwin

Average trapping/excellent flow:
Fram HP series

..........except the ToughGuard..........

The search feature works well on OSO, try it sometime, or just read something else if this is so bothersome.

Re: Marine Lubrication
 

Hydro, haven't read the whole thread but haven't seen you touch on Allison oil, have you ever heard of it? What can you tell me about it? We have used it at the shop in Ohio but want to here what you think.

Re: Marine Lubrication
 

I remember reading that the ToughGuard is one filter Fram makes that has good internal parts...most Fram filters would be ok if the relief valve and assembly were a bit more sturdy.
The HP/racing series are great on flow but not trapping and that is where the k&N's have a niche'.

Aerospace Industries INC. makes Alisyn synthetic oil. I do not have a ton of info on them but from what I have seen of the 20W-50 synthetic and synthetic marine gear-lubes.. they can go toe to toe with most premium synthetics.
