My son bought a nice little S-10 pickup. 1993 low miles 75k, 4cly, 5sp. He thought that he wanted to use synthetic oil in it. He bought Castrol synthetic oil. It was not cheap. He drove the truck to college three days, three hundred miles. It was two quarts low on oil. We thought that it might have not been filled to full after the filter change. We filled it up and he drove it two more days. Another quart low. We dropped the synthetic oil out and replaced it back with regular oil. Now he drives it five thousand miles between changes and it only uses 1/2 a quart. That was my first useage of it.

i run Castrol Syntec 10w30 in my '06 Toyota Tacoma
pickup...doesnt use a drop in 5000 miles when i change it...Toyota recommended 5w30 but i just think that too lite a oil to run in Texas heat.

Is your 2000 Taurus designated as a "flex-fuel" vehicle? Even if it is, apparently by 2006 there were a LOT of problems with folks attempting to run E-85 in flex-fuel Tauruses out in Nebraska.

Run E85 in a non-flex fuel car at your own risk. Manufacturers say "don't do it", that's good enough for me.

There are many synthetic and so-called "synthetic" oils on the market. Mobil 1 has been around for over thirty years and has an unblemished reputation. That's good enough for me. Many high-end cars come from the factory with Mobil 1. I have a friend who is a powertrain engineer with one of the OEMs. He said they were having a problem with piston rings that they eventually fixed by changing materials. They could not reproduce the problem when running Mobil 1.

You may say that today's engines are "BS", but how many cars from the fifties and sixties went over 200K miles with no engine maintenance other than oil changes?

Synthetic oil is no problem because you can switch back if you start leaking oil. I definately would not run E-85 in that vehicle. E-85 is VERY hard on non E-85 fuel components like the pump. Gerard

Yes, but why, yes but it "may" cause some problems.

I see no benefit to running synthetic, unless you are in a very cold climate,and/or you plan to run it for 25000 miles. I do run synthetics in transmissions, and rear ends.

I know a few people who consistaly run E85, and yes one is a Taurus. He had some problems with gaskets on the intake, and I think he had to repalcethe injector Orings, but nothing seriously major. OTOH, I have one friend who had a Buick who tried it once, I dont know what all happened to his engine but it cost him a small fortune to get it fixed.

I have been running Mobil 1 in my Fords since the early nineties and think it is great. I even run it in my MTD lawnmower. I almost started looking for another brand when the price went up a few years ago to over $5 a quart. I have found that by shopping ahead for sales and rebates I can buy it in the $4 range and sometimes even in the high $3 range per quart. By changing my own oil it doesn't cost much more than at an oil change place and I know what I have. Of course I don't believe that I have ever changed one yet without spilling or getting a little oil on myself.

Hello heikemper,
I like mobil 1 as well.

Good stuff....................Guido.

Hello BCnT,
If the 5w 30 is specified that is what you should use. There are cars now that use a 5w20.
That is what you put in, not a problem, or the OEM's would be bying a lot of engines.
Oil weight is mandated by the engine tolerances and operating temperature, the lower the oil weight, the tighter the clearances. That is a reason not to use a heavier oil weight then specified. It would be too thick and wipe bearings out the their tickness.

all ford motor oil has been semi synthec for several years, your car pobly had synthic oil in it from new, i read in a trade mag that all cars have had synthic oil in them for years

ASEguy · Oct 18, 2010

They both become 30 weight at operating temperature. The lighter weight in the multigrade oil is all about start-up lubrication. Most engine wear occurs at start-up. We started seeing the switch around the time we started seeing overhead cams. Those more modern engines usually have the hardened cam journals running in an aluminum head with virtually no wear due to hydrodynamic lubrication. Hope this helps. Gerard
