2002 Mountaineer/Explorer Synthetic Oil OK?

Looking to use Mobil1 synthetic in my '02 Mountaineer with the V8 engine. I have always been a fan of the Mobil1 as I have seen fuel mileage improve using their 10w30 and my other vehicles go around 150,00 miles with no engine problems at all. Question is would using the synthetic oil void the warrantee? Thanks Stephen

synthetic oil doesn't void *any* warranty.

I have a 2 year maintenence / service contract with my 2003 XLT. I get free standard maintenence every 5000 miles. My Ford dealer will not put in Mobil

1, but will put in Ford's synthetic oil. I just have to pay the difference in the oil cost. The Ford Synthetic oil is required on the 2003 V8. I've used Mobil 1 on all of my vehicles since my 1987 Taurus. I sold my wife's 1994 Toyota Camry 3 months ago. It had 125000 miles on it. I still used no oil between changes every 7500 miles.

Is there any non anecdotal evidence for it being better?

synthetics have a higher temperature before viscosity breakdown, lubricate better than dino oils and since they are synthetic, are indirectly more environmentally friendly.

Do a search on "synthetic oils" on the net, you'll get all the scientific information you need.

The difference in the viscosity can affect the engine, which is designed to run on 5-20. I wouldn't put in anything but what they specify!

Synthetic will NOT void the warranty. Ford's 5W20 is a semi-synthetic already. Mobil one just recently came out with a 0W20 that meets Ford's 5W20 spec.

I have 2 vehicles past 200K and 1 at 185K... always synthetic, 7500mi oil changes.

92 Explorer XLT - 185K 88 Bronco II - 220K 85 Buick Century LTD - 280K

They use no oil between changes... gone synth 10yrs ago, and won't go back ;-)

Used to be, you had to provide your own oil at a service station - or do your own oil changes. Nowadays, most service centers have synth on the menu. I have used several different synth oils, and haven't noticed any difference between them. I haven't used the Walmart store brand tho...

I don't know if appearance means anything, but the synth coming out looks better after 7500 than the regular oil did coming out after 3000...

I have had the following success stories..

1980 F150 134,000 1986 F250 118,000 1985 Thunderbird 142,000 1993 Jeep Grand Cherokee 125,000 1995 Chevy Astro Van (work truck 208,000 !!!) 1996 Explorer XLT AWD 112,000 (still have it)

All running GREAT , and not using a drop of oil when I sold them. To me that is a testament

to how good DINO LUBE works when changed at regular intervals!

5W-30 is lower in viscosity than 10W-30, and 10W-30 is lower is viscosity than 40W. Viscosity is like internal friction of a fluid. For example, molasses has a higher viscosity than water.

The period of most engine damage is upon startup; lower viscosity oil will distribute throughout the engine faster, will not bypass the oil filter as long, and will provide higher fuel economy.

The weight of the oil must be increased when the oil pressure cannot be maintained (normal engine wear) or under high temperature or high stress applications.

It is advisable to stay away from double weighted oils with a wide weight range, i.e., 5W-30, since the excessive amount of polymers necessary to increase the weight to 30 have been shown to cause deposits on piston rings; which decreases piston ring pressure.

I thought that camshafts, regardless of whether is it mounted in a cast iron block or aluminum engine head, doesn't actually make physical contact with either of these housings, but instead rotates on journal bearings made of material independent and inconsequential from the housing material, whether engine block or head, whether iron or aluminum. In this sense, the camshaft would not have any lubrication requirement variation simply because it was either in an iron block or alum head, unless it had to do with the mechanical interaction on the camshaft between a pushrod and overhead valvetrain, but I doubt that one type strains the cam much more than another.

Cam in block motors use a steel/copper/babbit bearing..... three layers being a steel sleeve lined with copper in turn lined with lead/tin babbit (modern materials may vary). OHC motors featuring aluminum heads usually have the camshafts rotating in the mother material... i.e., the head itself. Other variations include the camshaft being subjected (or not) to crankshaft windage, the camshaft being located above or below oil flowing from valve cover areas, metallurgy, design (in load bearing capability, lubrication requirements, proximity to the edge of self destruction, PSI loading at points of contact - including but not limited to valve spring pressures at rest and open, shear resistance of the lubrication medium..... shall I go on?).

A short trip through history can reveal many of the innovative ways various manufacturers accomplished what they wanted. The old Chryslers with the 'automatic' that shared oil with the motor (not to mention the old Austin Mini family doing the same with their manual transmissions), or the British Leyland 'preselector transmission'.... you'd move the shift lever and it would patiently wait for you to apply the clutch so it could complete the shift for you. How about the old 'semi-automatics' featuring a torque convertor combined with a clutch (in the case of the Beetle, it was vacuum operated and controlled by a switch built into the stick.... no clutch pedal).

The automobile has been around for over 100 years and I can assure you that there have been countless unique approaches to various operating requirements.

Nothing is cast in stone and it can become dangerous (or at least expensive) to assume things without research.
