Well, I went and did it. I ordered a new car over vacation. So now I face a new question. What oil to use. Because there are differences in detergents used in different brands of oil, it is important to start with one brand and stick with it through out the life of the car. That is how I got my little Vega through 12 years and 100,000 miles and compression still meets specs. I have run nothing but Quaker State 10w-30. But the last time a I got a new car, syn-oil did not exist, at least not on the car market, we used it in the lab though. Back then, it cost $1000/gal. I must admit I have not kept up on current technology as it concerns motor oil. Can anyone on the net point me to a source of UNBIASED information on syn-oils and their advantages over natural oil. I know that oil has two functions, clean the engine, and lubricate the engine. I change oil often to keep the engine clean. Any good oil, natural or otherwise, will lubricate long after it gets too dirty. Here in the midwest, there is a lot of dirt in the air, oil gets dirty fast, and so I change my oil three times a year. Breakdown is not an issue for me. I don't run the engine that hard or the oil that long. Is there really any good reason to run syn-oil? Somehow, I just know this is going to start a debate. Richard Piner piner@pur-phy.UUCP

My understanding is that most major 10w30 or 10w40 are completely compatible. > Can anyone on the net point me > to a source of UNBIASED information on syn-oils and their advantages > over natural oil. This discussion has gone on at least twice in this forum. The major points for synoil appear to be its long resistance to breakdown and its superior performance under extreme operating conditions. The petro oil advocates claim that the detergency is the big factor and that it wears out in synoil as fast as petro oil. There have also been lots of stories pro and con about experiences with synoil. Personally, I am running Mobil 1 5w30 in my 'new' car and have for > 30K miles and am very pleased. My old car is still on Quaker State 10w40 with much more frequent changes. > Somehow, I just know this is going to start a debate. Doesn't everything in this group?
