New oil from Driven
 

Always looking for more film strength and higher oil pressure but a blend at 17/quart?

Wonder how it actually compares to other 25w-60’s ? Like Torco’s full synthetic for example? This 5 gal would be $43.20 a gallon

Found this about the Torco 25w-60

• 100% Synthetic Formula utilizing Group III, IV, and V base stock
• mPAO base and friction-reducing moly increase horsepower and torque
• Shear-stable polymers resist viscosity thinning under severe conditions
• High solvency synthetic ester technology prevents deposit formation in highly loaded engines
• Combined primary/secondary zinc package lays down an antiwear film fast and keeps it there
• Moly and Zinc additives enhance each other to form protective, low friction films

Steve talks about it on his channel. He has since had an update after PRI comparing it to the competition. Also, a 25w-50 coming out.

never knew about this one , thanx BS er

I won’t come near anything torco after they changed their $21qt RTF trashed 4 of my drives in a span of a few years.

Driven has always seemed to be a quality product.

How did you figure out it was the oil ?
What drives?

Imco scx-4s. The gear lube went from a deep blue color to a green much like typical Mercury/quicksilver gear lube. Drives failed for the first time shortly after. Imco, who strictly advised to use only Imco rtf shortly after came out with their own gear lube.

Shifts are much smoother and plugs are much cleaner after putting in amsoil sever gear.

gave the last full quart of torco rtf garbage I had taking up space as a white elephant gift last weekend.

Response from Driven after I mentioned I use MR50 .Daniel,



For what it's worth, offshore racers prefer our GP-1 20W-50 in their engines. The GP-1 is blended with Pennsylvania Grade Base Oil, which provides tenacious clingability and exceptional film strength, along with enhanced levels of anti-wear chemistry. I would expect better oil pressure upon switch.



Antiwear is critical when it comes to marine engines. Under 'normal' operating conditions, marine engines are under 100% load, 90% of the time......as they are constantly battling the resistance of the water. Compare that to traditional passenger car engines, which are typically at 100% load, maybe 10% of the time. This simply equates to marine engines being under far more stress and more susceptible to wear...hence the need for a higher AW inhibited oils like Driven. Modern, licensed engine oils are formulated to be catalyst compatible, and because of this, have seen a drastic reduction in anti-wear chemistry.....which when used, may promote more pronounced wear to the engine valve train components.



Driven Racing Oils are tailor made / specifically formulated for the protection of the critical valve train components of an engine…but are not ‘true’ marine lubricants like those sold via OEM (Original Equipment Manufacturer). With the advent of the marine FC-W classification and the benefits/improvements that FC-W oils offer marine engines as compared to traditional automotive engine oils, FC-W certified oils are the clear, best recommendation for these applications.



Bottom line Daniel....I have long recommended Driven Racing Oil.....specifically our GP-1 High Performance Engine Oil, in marine applications, but under the caveat that the aforementioned are not catalyst safe due to their high levels of anti-wear. If you consider the GP-1 option, the wear protection would be phenomenal, but it should be made clear that the GP-1 options are not 'marine' FC-W certified, and that accelerated / frequent drain intervals would be critical.

That’s interesting I also use mr50

GP-1 looks interesting. Was trying to find a fresh oil analysis to get the chemistry.

Synthetic blend is a benefit. It has better film strength at extreme pressures from the conventional oil. The full synthetic extreme film strength tapers off, where the conventional is linear.

Reasonably priced.

The SP rated oils are pretty good. Low calcium and high zinc. (1000ppm zinc - 1200-1600ppm zinc)

SP rated uses magnesium as a detergent. It doesn't clean off the zinc like the calcium.

VR-1 has the better type of ZDDP. Not sure what GP-1 has

This one time at band camp I installed a distributer in a way where is it didn`t turn the oil pump.
I idled the engine for 10 minutes on the hose.
Another 10 minutes at the launch warming it up.
I got on plane at 1500rpm took it to 2000rpm for a minute before I realized there was 0 Oil pressure.

Thought for sure the engine is toast, cut filter open expecting the worst but it was clean.
Oil was clean, no glitter.
Ran it after that for half a season and every filter was still clean.

Kinda sold on MR50 after that.

I've been running driven oil in Unleashed for about 10yrs after trying a lot of others and it cured my oil pressure issues instantly and everything looked good after freshening a few years ago. Lake Speed Jr. gave me excellent customer service (used to be part of Driven) and now I watch some of his YouTube videos. This new SM oil is very interesting and I'm sure it will be great in the applications intended.

Been GP-1 for several years. Best oil i have used to date.

offshore...do you mean SP oils? SM rated oils were from 2009 era.

How does the driven oil compare to Schaeffers?

SM oil (SMoil) refers to the new Steve Morris racing oil released by Driven.

Penn grade
 

I have been using penn grade the green oil anyone else try it
