Oil Change
I am going to change the engine oil this week. I am planning to use Mobil Syn. Does anyone know can I use the Syn oil? And which should I use?(10W-30?5W-30?) And any tips of oil change? Thanks.

As I understand it really isn't the best thing to use synthetic, unless the car has always used it since the very first oil change, if this is the case I would go forward if not,stick with the non synethic mobil.

It won't damage anything, it is superior in most respects. The one problem area you may notice is that the oil will seep past older seals and gaskets, where the regular oil did not.

you could go halfway and try a synthetic blend.

Mobil 1 is a true Hydro carbon. It is the puriest oil available without any impurities because it did not come out of the ground. It ws man made. Mobil has/had a patent on this. Any other syn-oils are something else. Unless the patent ran out. So..................

Synthetic or not?
I used Synthetic in my XT Turbo, but I wonder about how much better synthetic would be on a non-turbo SVX. If you use a quality product and change it every 3,000 miles, I wonder if there are any significant benefits. Mine is a '92 LSL with 142,000 miles and she uses almost no oil between changes, so thus far I've stayed with regular oil. Does anyone have an opinion as to the best regular oil? Castrol? Kendall? Havoline?

oil
It is a myth that you can not use synthetic oil unless the car has been using it since new. You can start using it at anytime, and you could even switch back to regular oil if you wanted to. The biggest advantages of synthetic are less friction at startup (which is where a lot of your engine wear comes from), and superior resistance to breakdown. In fact (I've posted this elsewhere also) I just read an article about Mobile 1 synthetic oil that said that Mobile engineers stated that if vehicle manufacturers started recommending oil changes at 10,000 mile intervals, Mobile 1 would have no problems meeting the requirement. It's that good at resisting breakdown.
It is also a myth that you can not use synthetic oil in a new engine. Porsche, Lamborghini, Mercedes, Ferrari and Dodge (the Viper) are some examples of manufacturers that use synthetic oil in some (or all) of their cars right at the factory. David |

This months hot rod magazine had a good article on synthetics - they even swapped the dino oil out of an old car with synthetic and made 10hp or so at the rear wheels. I have been running synthetic in mine for 60k and my wifes for 22k and have not seen a problem with more oil leaking. Both were run on dino oil up to 100k miles and made the switch then. I dont think I've seen 10hp at the wheels or even 1 hp but it does make me feel a little better each time I watch the tach wrap around to know I have some sort of added protection in there. My wagon, on the other hand, would leak even if it was full of straight 30 dino oil but after 270k hard miles it still can bark the tires into 3rd and when I last popped the valve covers it was nice and clean in there.

i agree that synthetic oil is vastly superior to "dino oil", but Beav is right---your seals had better be good because the synthetic oil will leak right through 'em. i used Mobil 1 in my 928 and it started leaking oil like the Exxon Valdez. back to regular Castrol, and it settled down a bit.
BTW, the UPC code on a case of Mobil 1 is apparently just for 1 quart. bought a case at a local dept. store and a spaced out teenager scanned it and proceded to charge me $4.xx for the case. heh heh. Alan

It's been a few years but the last time we did a spinning load test Kendall GT1 came out on top by a significant margin. The other name brands were pretty well grouped together about 25% down scale and the off brands were trailing way back.
