amsoil is about the only synthetic oil that still has the zinc content that's required for our engines and there is no need for any additives.

I have heard that the newer Mobil 1 High mileage full synthetic has a nice amount of zinc. Have you heard that?
Ok pontiacgp, here we go again. :lol:
"conventional oil is no match to synthetic oil and grease"
I really hate blanket statements like that.
Is syn better for break-in?
Is syn better for a older motor?
Is syn worth it is a beater?
Is syn better in a rear?
I think all oils have there place. The right oil used in the right situation.
My race motor was built to run thin oil, tight tolerances. I use Brad Penn racing/high performance 0-30. It is a syn blend.
The syn part helps with lubrication/flow but the base stock, dino oil, helps it cling.
The car sits for long periods and I want a layer of oil there before the key is hit.
My Wifes SV6 mini van has gotten a steady diet of Mobil 1 0w20. Again these engines were/are deigned not to need the zinc/phos and to run thinner oil.
My beater wagon gets the thickest oil that is on sale. 😳
Also be carefull on buying "synthetic oils", some ARE NOT synthetic.
There is no standard in the industry on what is and is not synthetic.Where's Nader?
Castrol syn is highly refined dino oil, not syn.
Amsoil and Mobil 1 are syn.
Oh, Mobil 1, Rotella, etc is subjected to the same rules as anyone else, so it has to meet the same levels of zinc as the other oils.
Mobil 1 racing oil, read offroad, does have 2x the amount of zinc/phos as their street oil.
Brad Penn is similar street vs race.
Let's make sure we are comparing apples to apples.

shotgun....you can use any oil you like and you can disagree with the fact that synthetic oils are superior to conventional oils. Breaking in a new engine is the one area that petroleum oil is better for than synthetics and that is due to one of the weak points of conventional oil, petroleum oil has a very low film strength which is ideal for breaking in a new engine. I run amsoil synthetic oil in my street car which has at least 300.000 miles. And if you read my posts about synthetic I only talk about ansoil so I am comparing apples to apples. I'm putting another engine together and I'll be running synthetic again....I'll also run synthetic oil in my transmission ans I'll run synthetic oil in my standard transmission when I install it with the new engine...oh and I use synthetic grease in the rear end too...the engine spools up quicker with synthetic oil, the transmission runs smother and the rear end turns easier with synthetic...and all the race cars from super stocks to limited late models at the track run synthetic....and there is very few engine failures but I guess they know nothing....they should all have you on speed dial to get your input before they do anything.... :lol:

where did you read that? Synthetic had nothing to do with crude oil
"Synthetic oil is oil consisting of chemical compounds which were not originally present in crude oil (petroleum), but were artificially made (synthesized) from other compounds."
"In the mid 1960s Chevron U.S.A was the first to market and produce a complete range of 100% synthetic Polyalphaolefins based lubricants"

From Mobil 1's website.
All motor oils are made up of base oils and additives. In general, fully synthetic motor oils contain non-conventional, high-performance fluids and a system of additives to help prevent wear, keep an engine clean, flow easily, maintain viscosity, prevent rust and reduce friction. The result is a lubricant that remains liquid and slippery under the widest possible range of temperatures and engine conditions.
Now i may be misunderstanding this statement, but i have read or seen in another place that stated the same. I'm by no means saying that there is not a benefit from using synthetic oils. My understanding is that "synthetic" usually pertains to the the additive package. And some of the newer oils are claming that there base is synthetic. I take that to mean that they are taking conventional base and reformulating it(can't remember how or what they do to it exactly), which would no longer make it a conventional base.
I don't think(and i could be wrong) that they are actually producing a completely man-made oil. On a side note if we can do that, why couldn't we also be making completely man-made gasoline, after all that comes from crude too.
Edit-I looked on the wiki entry that you quoted and read about the synthetic base stocks. So according to that i'm wrong. What really irritates me is the info is so messed up that depending on where you look you can get or interpret different answers.

Maybe your right, I never read that before but I'll look for some info on it...and wiki isn't always right.....that's interesting what you found on Mobile 1's web site tho
