Don't do it man, its a waste of money.Here is an interesting site where this guy sent his Mobile 1 off to be analyzed by a professional lab. He did so two times once at 7000 and the other at 8600 miles. The conclusion was, both times, that the oil was way cleaner than the average that is tested. http://users.ev1.net/~shinglin/cars/oil/oilrpt.html After the results of the first test the lab suggested that he push the oil change out another 1000 miles. Then, after the second test the lab tech commented that it would not be possible, from the condition of the oil, to tell the difference between the 7000 and the 8600 mile oil drains, and that the oil showed no signs of breaking down. The tests are run by Blackstone Labs, an independant company that does nothing but oil analysis. Here is there web site... http://www.blackstone-labs.com/ I believe the test is right at $20 including shipping costs. They results are very detailed and can tell you all sorts of stuff before they become problems. ------------------

I believe it!! My work truck is an S10 chevy 4.3 litre with 250,000 miles on it and I have alsways tried to use Synthetic oil in it.. I change the oil at 7500 miles.. The oil pressure is still 75 psi @ cold idle and 40 psi @ hot idle.. It's amazing..

I know that many of you may never see extreme cold tempatures, but here is a test I saw with my own eyes in a lab. Mobil 1 was put in an cold chamber against valvolene (not synthetic). Tempature was -40 F. After two hours the Mobil 1 had thickened to a honey like consistancy. The Valvolene turned to paste. It felt like Vasolene. There is no way that it would flow at that temp. If you live in an area that gets below freezing temps, I would have to recommend Mobil 1.

Used mobil 1 in my escort for the 1st 4 years and have never had an internal engine problem. Now I have used it in my 98 f-150 for 3 1/2 years and have also had good luck with it. I also change my mobil 1 at 7000 to 8000 miles just because when I used to check my oil it would still look as clean as when I checked it at 1000 miles! With that kind of milage it almost ends up costing the same. My mustang uses texaco havoline and is changed regularly at 3000 miles.joe

i run mobile 1 in all my cars. i run it 5000 miles and change the filter and add a quart. then i run it 5000 more miles and change the oil and filter, then start over with the cycle.
(true story) my wife's oil pump went out on her 4.0 explorer and she continued to drive it for over 20 miles, she got home and told me it was making a funny noise. (understatement) it had 0 oil pressure and was rattling like crazy. i replaced the pump and the oil pressure came back up with no noticeable damage. does not even rattle on a cold start or anything. i attribute all this to the mobile 1.

The local Target store over here was selling the Mobil 1 for $2.94 a qt, what a deal A month or 2 ago it was going for $4.39 a qt. I bought 3 oil changes for the 98 f-150, it takes 7qts for 1 oil change(damn!). So I thought I better stock up.joe

Hmmm, I wonder if I can run that stuff in my Harley. I put it in the Supercrew every 5k already. I imagine it would work even better in the air-cooled v-twin.

If you are pleased with Mobil one, you should try Amsoil Series 2000 0W-30. It will go 1 year or 35,000 miles on a single change. All the specs on the Amsoil surpass Mobil one, at least from what I've seen in literature received from tests conducted. The only catch is that you have to change the oil filter at 6 month intervals and then top off, which can be a bit of a pain. In my '93 Taurus I've run synthetic oil, trans. fluid, and have run the trans. fluid in my power steering as well. Started using it at 2,000 miles and now have 84,000 - no motor, transmission, or power steering problems at all. I run it in my '96 Saturn too. In the '00 Vert I've already got it in the manual trans., rear end, and power steering. Have to get more break in miles to start with the motor oil. Winter starting is no problem and I'm still on the original battery in the Saturn, which has to say something for the oil in the cold weather. I don't sell the stuff, just use it, so I have no reason to push the Amsoil but I can attest that it really is good stuff.------------------

Scott(69Mach),
A friend of mine has a '99 Harley who considered changing to synthetic oil. However, when he asked his neighborhood dealership about it, they strongly discouraged him from doing it and even mentioned that it may affect his warranty......SO - If I was you, I'd checkout that possible downfall with your dealership before making the switch..... Good Luck!Ryan

Great timing on an aritcle in Hot Bike magazine wherein they ask a bunch of oil makers a bunch of questions including oil longevity and why and when to change it out. Turns out, it's the additives that are the first to go. These additives keep your valve guides working longer and keep combustion contaminants (gas and carbon) and acids from accumulating in the oil and breaking it down. Mobil 1 specifically recommended changing at the recommended frequency (yeah, they're selling oil), but stated that the oil would last quite a bit longer than that. For me, I'd rather cough up $$$ for oil changes than for valve guides so I'll stick to my conservative 5k interval with synth on the street car.

Like you said, they are selling oil. Thats like asking a exterminator how often they should spray for bugs. Call me a synic but I don't believe a f&^%$(g thing that the oil companies tell us.Bet you they didn't ask the guys at Amsoil, as those guys recommend greatly increased change intervals. Gee, how is it that only this one company can make oil that will go 35,000 miles? Hmmmmm, are they special? No. Do they hold a patent on some special goop? No. Do they have more money to pour into R&D? A big no. Then maybe, just maybe, the oil companies are totally full of ****! ------------------

Yep, AMSoil recommeneded double the manufacturer's interval or annually, whichever comes first. They also had the caveat that you use a high quality filter. No Fram filters need apply...
