mobil 1 5w-20 super synthetic with a k&n oli filter.

Just curious, does everyone here pre-fill there oil filter? and wipe alittle bit of oil on the rubber gasket, before screwing it on?

Oil the gasket, yes. But the filter prefill depends on the angle of install for the filter. Some you can prefill and install with no loss, others that mount horizontally end up spilling too much during install.

No, I install it dry (with some oil on the O-ring.)

Mobil 1 10W30 full synthetic... and I put my filter on dry with oil on the seal...Why fill it in the first place? Your engine has enough residual to not hurt it when you start...

Just had my first oil change 2958 miles, it's 6 months old ('06 GT Premium Coupe). Told service manager I plan to have them change it every 3000, he said not necessary, every 5000 miles is good. Seems like an honest answer so 6 months or 5000 they are going to get my business. It might cost a little more BUT they do all the work, I won't have to worry about the warrantee, they check everything and dispose of the old oil. I trust Ford will use the right stuff.

What oil to use? In our household it's REDLINE synthetic 5-20.
But I will admit there are vehicles that get Motorcraft 5-20 & Mobil 1 5-20 also.
Any of it is fine as long as it passes Sae/ petrol specs .

But who reads the bottles anymore?

not true, there are manufacturers that use synthetic from the factory

Your VCT might not care for the 30W though.

Oil Change Question

Don't have it yet, but when I get my 07 GT vert which I've ordered, I was planning to immediately change to Mobil 1 5W20.

I was thinking this was ok; it that right? Would appreciate some clarity on the suggestion that one should wait until after 5K miles for the engine break-in. Thanks.

I Used Mobil 1 Since 1979 In All My Autos And Many Others Never Had A Oil Problem Ever. They Have A 0/20 Mobil 1 ,i Used This In My 01 Gt In Cooler Weather May See Some Advantage With This.i Used 15/50 Mobil One In My 70 Mustang Still Runs Great.

You can change to M1 right away or wait 5000 miles, does not matter. I really feel that MC 5w20 is all these engines need and there is nothing to be gained by running M1 except longer OCIs. M1 won't hurt and you won't have any oil-related problems using M1 but then again you wouldn't by using MC either.

My car, I ran the OEM oil 4800 miles.

I just get mine changed at the dealer I bought it from. I get lifetime oil changes for $19.95 and I get to have free coffee and freshly baked cookies while I wait. I also get to check out all their new Mustangs while waiting. Not bad. The only downside is the longer wait (about two hours) but being retired I'm in no rush.

Ok, lets back up a minute (post or two). Some vehicles do come with factory fill of synthetic, Porsche, Corvette, Viper, etc.
However, these engines have been pre-run, maybe even dynoed before installation. Some synthetics have different base carriers in their formula.

Redline does not reccommend using until at least 3000 miles are on the engine. The ester base stock is so slick, the rings may not seat in a new engine, hince the breakend period.

However, I have witnessed NASCAR team add mobil 1 to a new engine setting on the dyno, fire it up and crank it to the max with no apparent damage. Now I don't know about the assembly clearences inside of that motor, only they had to be to the ultimate specs if that engine would survive it coming life at max RPM's for 500 miles.

Basicly oil (dino) is oil, it just has a different additive package in it depending on the manufacture.
Synthetics, thats a whole different ball game. you got your 100%'s, blends, and all sorts of base stock to begin with.
Just read the bottle, or website. check for NPI ratings, seal or logo.
And stay away from the plain black bottles that just say synthetic oil and have the weight written under that.
Believe it or not, its on the web, thats where it should stay, and not in your engine. If in doubt use Motorcraft 5-20 factory fill. You will not go wrong.

I use Motorcraft 5-20w and change the oil and filter every 2,500 miles. Did the first one at 1,000 just to get the junk out of the system. Would never let anyone else change my oil/filter. Just wipe some oil on the gasket and put the filter on dry. My 1992 Explorer Sport has 269,000 miles on it and doesn't drip a drop of oil - places like Jiffy Lube will over torque the pan bolt plus they don't really have any investment in your ride. So, DITY.

This is from their fleet newsletter. It pretty much summarizes all of the reasons for the use of 5W-20 that we discuss here. It also puts the "only for gas mileage" theory to bed.

https://www.fleet.ford.com/FFH/Rental05_23_06.asp

"Why 5W20 Oil?
Some customers are reluctant to follow Ford's recommendation to use 5W-20 oil in their engines based on the incorrect assumption that Ford and other Auto Manufacturers only recommend 5W-20 oil in order to increase fuel economy. Using 5W-20 oil can increase fuel economy by about 6/10ths of a percent compared to 5W-30 and more if you are currently using a higher viscosity oil. This equates to an additional savings of 125 million gallons per year when used in all applicable Ford vehicles. Since its introduction in the 2001 MY, 5W-20 oils have saved up to 640 million gallons of gasoline in the U.S. or an equivalent 5.6 million metric tons of carbon dioxide emissions.

5W-20 oil is a thinner oil with lighter viscosity that creates less drag on the crankshaft, pistons and valvetrain. Additionally, the oil pump can pump thinner oil more easily, improving oil circulation. Any increase in fuel economy may not be noticed by the average motorist. Machined internal engine parts are more precise than the parts of 20 years ago. This means that clearances between moving parts are smaller and more exact. Thinner oil such as 5W-20 can flow more freely through the engine while still filling the spaces. Thicker oil is harder to push through the spaces between the parts. This causes the oil pump to work harder, which in turn increases oil pressure while simultaneously decreasing oil volume. A lack of oil volume results in a decrease of lubrication and cooling, which may decrease engine part life.

The lighter viscosity of 5W-20 oil flows faster at start-up compared to higher viscosity oils, which helps reduce engine wear in critical areas by lubricating parts faster. Valvetrain components at the top of the engine require immediate lubrication at start-up.

Oil additives are not recommended as noted in the owners manual. The American Petroleum Institute (API) certifies that oils such as Motorcraft 5W-20 already contain the necessary additives for friction, detergent, etc... The addition of additives may interfere and react with the additives already present in the certified oil."
