"Mobil 1 Extended Performance

You've never seen an oil like this before. Mobil 1® Extended Performance is a new high-endurance motor oil with 36 percent more anti-wear additives and 37 percent more cleaning agents than current Mobil 1 formulations. It is a fully synthetic formulation that helps extend engine life, reduce oil breakdown and minimize engine wear -- all while helping to keep your engine clean. Improvements that add up to exceptional protection for 15,000 miles. Guaranteed. " ...from mobiloil.com

Mobil 1 Extended Performance

Dave...

Well I believe the idea is to change your filter only and top off the existing oil. I can see it saving $ but I can't see myself changing the filter without going ahead and changing the oil too. 

I am the same way Marshall, I am not just going to top the oil off and change the filter. I am changing everything lol.

I agree with both ideas.

The Purolator Pure One and Mobil One filters have synthetic elements that are better than run-of-the-mill filters.

I've had oil analysis done on our truck and my car (Subaru) and the [conventional] oil is fine after 7,000+ miles of use.

Some heavy trucks have gone to 40,000 mile changes, but have better filters.

It is my undestanding also that the lag is in the filters at this time.  I also use the Mobil 1 filters though they  are expensive because I cannot always get to my oil changes when I would like and this gives me a added barrier.  Also the cold temps of course.

Now our 01 Chevy Venture that we just picked up in January since our old Ford Windstar bought the farm has a oil sensor in it that tells me when to change the oil.  This is annoying because my wife drives a ton and when the light goes off she haunts me until I change it and it has already gone off once....  and the oil was crystal clear when I purchased this van.  This time it has the Mobile 1 oil and filter in it so we will see if it makes a difference with the sensor on the van.  If it keeps going off this fast I will have to change to dino oil and a cheaper filter.

We shall see.

for 30 years now we've run our otr trucks around 50000 miles without changing oil. (filters only about every 12000) engines will run a minimum of 400,000 miles before requiring overhaul. and thats on dino oil. as much less strain as automotive engines have on them, running a good oil 15000 with filter change at recommended intervals should cause no problems.
Personally in my powerstroke i run Rotella T 10-40 & change oil at 10000 miles with one filter only change  at the half way mark.

Chris, I only have one car that has the Oil life monitor system on it, and it is the early kind that GM put out.  It does seem that Mobil 1 could be working, but that car doesn't get driven much.  I think this oil life monitor that GM puts out is just for the regular oils, but am not sure.  They could probably improve them, as I can see GM making one that has settings for regular, Mobil 1, and Mobil extended lol.    I've never used the Mobil extended life oil just the Mobil 1.  It would be interesting as to what you find out, when the sensor goes off out of mileage or by the oil sensor.  

Yes oil has come a LONG way in the last 15 years. I have been worknig on Honda Auto for over 26 years & some of our cars are listed to go 10,000 before an oil change.

Me IM still old school I change my oil every 3,000 in all 4 of my Honda cars & in my GMC P/U.

Honda Oil Filters & an AC delco Filter for my Truck

As far as the Honda go all 4 have over 150,000 miles & still run strong.

Honda's oil filter is the best thing going. Like it states in the slick 50 comerical's When you first Start your eng This is when all of the damage is done.

NOT SO WITH AN HONDA OIL FILTER, you see they have a one way check valve in there oil filter that holds the oil in the top, so when you first start you car the O/H cam, rockers..... all get oil right away.

Most oil filters bleed down over night,  A lot of them clame to have a check valve But when you pull the filter off & you only get a filter's worth of oil out. You know it drained out from the motor. It should drain from in side the Filter screw for a while ~ enough to drain from the top down, Then you know its working.

I run OEM ~ Honda oil in all my cars & truck, It is proven to be one of the best oils out there

Mobil 1 Synthetic in my snowblower & in my Yamaha 660 /  4-wheeler

Just my 2 cents

That was some nice info there Buck101.  I really  appreciate it.  I wonder if Honda makes a SAE 30 for the OPE, and if it's better than Valvoline.  I might switch over.

Great theory. but not entirely true.  Modern oils prevent metal/metal contact . During startup the oil film that remains provides contact lubrication until the oil pressure builds. This boundary or contact lubrication creates much less friction than metal/metal contact . Once oil pressure builds there is "hydrodynamic" - pressurized - oil flow which eliminates almost all the friction load.

 An anti-drainback valve minimizes the time required to build  oil pressure., but doesn't eliminate it.  Some dry sump race cars have accumulators in the system with a shutoff valve. So you can open the valve, pressurize the oil system, then start.  But I'm not aware of  any  street cars with either system. So there is always some  boundary layer lubrication. Differential expansion between parts at extreme cold temps also creates a lot of wear.

Hondas are extremely well engineered. Our [2005 Accord V6] only has 8,000 miles and we're using Mobil one and Puralator Pure One filters because they have synthetic filter elements (so do Mobil One filters). We won't do our first oil analysis until the next change.

 We've done oil analysis on a 1997 Subaru (currently 156K miles) and a Ford van  (currently 158K) and with 7,000 to 7,500 miles between changes (conventional oil) iand it's still perfectly good - we could extend the drain intervals to 10,000 no problem. Throwing away oil with 3,000 miles on it is just creating high-grade waste oil. But the 3,000 mile interval is a faith-based religion so tribology does not sway anyone.

BTW, I learned about oil analysis in the Army with our old M60A3 tanks. Tanks always operate under high load, but seldom go more than a few hundred miles a year.  And they held many gallons  od oil - 30+ as I recall. The oil analysis measured the wear state of the oil, and also caught unusual wear patterns. 

There are a number of firms that do this. We use National Tribology - www.natrib.com.
