New Formula's of Mobil 1
 

Just wondering what the thoughts are on the new Mobil 1 formulas that are for "extended" milage driving? 15000 miles?!?! :eek:

Looks like the 15-50wt is only available in the extended life :rolleyes:

Good catch Griff! I didn't pick up on that when news of this new version of Mobil 1 hit this site a few weeks ago. Lou

If you want me to I will contact my guy at the refinerey and get the "scoop" from him.

What's not clear to me is what,if any, price difference will be for the different versions of Mobil 1. I bought 10 jugs of red cap at Walmart over the winter at just below $19.00/jug. I plan to continue to use the 15w-50 Mobil 1 and change it at roughly 12 hours even though the rebuilder (Sterling) recommended a 'qualified ' (shut it off, check oil level and smell dipstick. If oil level goes up or smells of gas-change it) 20 hour interval. The new Mobil 1 claims 36% more anti-wear and 77% more detergents which would prolong oil changes under normal driving conditions. Personally I wouldn't risk it with my blower motors that are set up just a little rich. That's just me. Everyone needs to do what they feel is right for themselves.Just one person's opinion. Lou

Mobil chemists reformulated the additive package. From what I can tell it is similar to the "heavier" additive package they put in Mobil-1 V-Twin. The additives hold up longer so that means the detergency is increased which helps to keep small particles suspended thereby decreasing the potential for wear on the engine parts; the package has greater volumes of friction reducers to protect metals from scuffing etc; and the package also has more corrosion resistance chemistry built in. I believe I read that Mobil uses boron for detergency; moly for friction reduction and a proprietary item for corrosion resistance. All in all worth every cent. Remember...competitive products that advertise "extended" to 15,000 miles go for up to $9.00/qt so this is a great improvement and bargain.

In a marine application however I am not too sure about doing "extended" drains as we hear more about water from condensation and perhaps small amounts from the reversion thing. I think it's just a better product and follow manufacturers recommended drains.

Many European cars are going to 15,000 mile manufacturer drains and that's why Mobil reformulated; to be positioned in this "new" and expanding marketplace. Eventually this will become mainstream in the auto industry.

Porsche worked with Mobil in an article I read and found that in combination with their unique silicon/aluminum engine block composition that 15,000 miles showed oil analysis that reported nearly no metallic particles found in the oil samples at several test intervals. Porsche has a very good oil fliter as well which is key in going "extended" drains. Also, they use a dry sump system that is very efficient. So "don't try this at home" unless your auto manual says to ..(in my humble opinion). :D

I really didn't intend on going this far with my boat motor. Just Mobil 1 20w50 changed every 30 hours with a Napa Gold filter. But with my auto's I am curious... I might try the extended and @ 7500 do an oil anaylsis.....

Re: New Formula's of Mobil 1
 

Is Mobil 1 (or any synthetic) really recommended for a marine application where there is potentional for moisture in the oil?

Re: New Formula's of Mobil 1
 

The Illmor engines have Mobil-1 15W-50 manufacturer recommendations and the oil cap says 'Mobil-1" 15W-50.

Additionally a Sterling engines company rep said they used Mobil-1 in their marine application engines.

The new "goldcap" has more corrosion resistant additives.

Mercury Marine told me they now have a semi-synthetic blend 25W-40.

So to answer your question 2 companies use it and racing teams do as well. Condensation is not a huge concern as it burns off and some have said that Royal Purple has saved engines that had some reversion. SO it's your call as always.
