oil change....snythic

I just got a used longblock with under 45k. I wondering if I should switch to using snythic oil ? What are the benfits of using snythic the regular?

it protects and lubricates better.

it protects and lubricates better.

So then it's worth it right? Dose it make the motor run a little better or dose it run a little cooler?

For a stock car, I don't think it makes a difference so long as you change your oil frequently.

I think if you used synthetic oil you'd still probably change the oil every 3k miles even though it can last 8k miles before an oil change.

Either way, I'd rather just change my oil every 2.5k and use regular motor oil than pay that extra money per bottle and it'll still be cheaper.

now if your car had a turbocharger or supercharger that would be a different story.

technically all of your engine components will have less wear in the long run. so your engine will last longer

So which snythic oil would you reccomend that I should use??Honda's,Valvaline,castro,redline?

redline is popular. honda's has to be good. i really wouldn't know though on that part. try to do research on it they should all be better than regular. unless it's like pepe's oil or something.

I just found out the answer to that question: Chevron Delo 400 Synthetic 0W-30 if you live north of Texas, and Mobil 1 0W-30 if you live south of Texas (southern states only).

Why? Almost half your lifetime engine wear occurs during cranking (confirmed by several engineer friends and also by Mobil Oil Company), so a 0W-30 is the right weight to cut wear down. The "0W" part means the oil gets up and gets going to the bearings the fastest during engine cranking at start-up. Therefore, a "0W" is the best. (A "0W-30" can be used where the manufacturer recommends a 5w-30.)

But why Chevron Delo Synthetic 0W-30 for anybody who lives north of Texas? Taking the "Dragnet" approach, "Just-The-Facts", look at the incredible technical spec sheet at http://bestsyntheticoil.com/dealers/amsoil/technical-data-bulletins/Specs-Ranked-June-17-2003.pdf and notice that Chevron, employing some of the best engineers and having some of the best labs in the world, have come up with a synthetic oil that has a Pour Point of -76 degrees below zero. BEST THERE IS. That low number means that their Delo Synthetic 0W-30 oil resists the bad effects of cool temperatures, indicating that it is going to flow better when the weather is simply below freezing as well. By the way, the Chevron oil's Flash Point is still OK at 419 degrees (any number over 400 is good).

South of Texas (any southern state), its fine to use Mobil 1 0W-30, since its Pour Point is almost as good as Chevron's Delo Synthetic, and Mobil 1 has a slight edge on high temperature Flash Point.

Also, Mobil 1, like Chevron Delo Synthetic, is produced by world-class, well-funded engineers with some of the best labs anywhere. This means Mobil 1 or Chevron synthetic have proper additive packages in addition to having oil that flows at cooler temps and hangs in there at high temps.

One note: If racing or pulling a trailer, you might want to use Chevron Delo Synthetic 5w-40 weight or Mobil 1 synthetic 0w-40 weight. However, the 0w-30 weights in both brands of oil would probably do just fine there too.

Chevron Delo Synthetic 0w-30 may only be available at trucking supply stores. Mobil 1 is available everywhere.

I don't work for Chevron or Mobil. I am an engineer (Mechanical/Aerospace/Computer) and I think you've got to go on the facts without ANY marketing hype.

It may be noted that Chevron sells the Delo Synthetic to trucking fleet managers who they know will see the numbers, so marketing hype is not going to suffice. That might be why Chevron has the best Pour Point while some other more heavily consumer-advertised oils don't.

good luck
