Thats pretty much what I said.Fredo said:It has been proven that synthetic oil will not cause leaks. If you put in a engine that already has leaks the leak will get worst, but who would want to waste money putting good oil in a leaker anyway.
6Stang7 said:Synthetics oils are not a waste of money. Does it cause a reduction in parenthetic power loss? Yes. Horsepower TV did a test were they dynoed a 00 Camaro SS, then replaced the engine, tranny, and diff with synthetic fluids and then dynoed it again. They got a gain of 8RWHP. There are three other advantages to running a synthetic motor oil. First, it lubricates better then conventional motor oil, which reduces the amount of wear on your engine. Seconded, it has a higher resistance to thermal break down over conventional motor oil, which also reduces the amount of wear on your engine. Finally, synthetic oil doesn’t have wax in it; therefore, it doesn’t leave behind build up while conventional motor oil does. Do these justify the additional cost of synthetic? That’s up to you to decide; however, I run Mobil 1 in my stang and wouldn’t run anything other then a synthetic. Right now I think Mobil 1 in the best, but only because there is speculation as to weather or not Royal Purple leaves deposits.

TheWolf said:They say to never break in an engine using synthetic. I will not use synthetic in my cars for several reasons. the cost, the fact that if you have a tiny leak somewhere, synthetic will make it worse. I use 10w-30 and 20w-40
Blown4.6 said:Yes, synthetic does withstand higher temps before breakdown. Unfortunately, you're engine will never, never, never see such conditions. Not even close. A $2500 pad lock is better than a $5.00 masterlock. But if you're locking a screen door, who cares? That's the point I'm making.
HP tv was advertising synthetic oils on that episode...when they are paid to advertise K&N, low and behold I saw them get 25 extra hp out of their LS1. Then, they added a cold air kit. Voila.....15 more horsepower! That was simply a paid commercial for K&N and then MAC cold air. Anyone who knows anything will tell you K&N might give you 2-4 hp at most, at the top of the rpm range. Cold air, has been shown to do almost nothing on a new car.
If you want to use Synthetic (and I do), go ahead. It doesn't hurt anything. But, the only ture benefit you're getting is an ability to go longer between oil changes as dino oil will oxidise to the point where you need to change it after about a year, regardless of miles. Synthetic will not behave this way. That's why I use it some of my vintage cars. I put like 250 miles / yeare on them. With dino, you don't want to let 8 years go by between oil changes, waiting to get 2k on the clock.

RGS0907,
How long did you let the car sit?
