Valoline SynPower 10-30w?
Anyone on this forum using this oil on their car. I just picked some up for my new motor after the engine break in. Well, won't be using for sometime since the motor isn't even in the car yet. I usually use Mobile1 oil on my engine but these were on sale at Kreagan/Checker auto.
I think they are normally $6+ but it's on sale for $20.00 per case/6, then mail in rebate, the total paid is $6.00 for the case for SynPower. Good deal!

Valvoline synthetic oils have a high ash count (you can get a data sheet from the manufacturer), that means high carbon which you do not want in your motor. Stick to a premium synthetic like Royal Purple, mobile 1, or Amsoil, they are all at or near 0 for the ash count.

It looks like the synthetic Valvoline is not THAT high in ash content at all....
less than 40 puts it right in there with other premium brands

For Valvoline synthetic that list shows <1.5% ash content
That list doesnt have much for ash numbers on other synthetics, but some more googling I found that Amsoil is <0.4%
Mobile1 isnt as low as I thought, at 1.0%
At any rate, use what you want but I prefer to use something lower ash content as that number right there is directly related to how clean the oil will burn and how much crap is left behind.

I was going to switch to Amsoil before I read this, no its for sure.

This may be a dumb question, but aren't metallic additives like zinc, etc., contributors to ash content? And, if so, does that mean that extremely low ash means low antiwear additive content? I mention this because of the recent thread on ZDDP, etc., additives being necessary for long engine life.
When we do ash analysis on rubber parts in the lab, a significant portion of the ash is metallic.

Ash% and zinc% seem to be unrelated from what I can tell.
From bajaman's link:
From bajaman's link:
% zinc is the amount of zinc used as an extreme pressure, anti-wear additive. The zinc is only used when there is actual metal to metal contact in the engine. Hopefully the oil will do its job and this will rarely occur, but if it does, the zinc compounds react with the metal to prevent scuffing and wear. A level of .11% is enough to protect an automobile engine for the extended oil drain interval, under normal use. Those of you with high revving, air cooled motorcycles or turbo charged cars or bikes might want to look at the oils with the higher zinc content. More doesn't give you better protection, it gives you longer protection if the rate of metal to metal contact is abnormally high. High zinc content can lead to deposit formation and plug fouling.

In my experience, ash is unburnt (unburnable) components that are left after a TGA (Thermal Gravimetric Analysis - used in analytical chemistry) analysis is done. This test is done by precisely weighing a sample of the material in question (in our case, an oil sample), and then continually monitoring the weight as the temperature of the sample is continuously raised, and portions of the sample vaporize or burn off. The first thing to go is usually the volatile portion. Next, polymer compounds, followed by carbon burning off. The ash remaining at the end is made up of stuff that did not vaporize or burn off at the highest test temperature. This usally consists of metallic compounds, silicates, etc.
Therefore, almost by definition, ash will not be "carbon."

yeah ive heard not to use syn oil in my motor all the time.. but then again the oil today is super formulated like from he double hockey stick haha!! if i run royal purple on my motor i dont see where it will kill my motor? it doesnt build carbon easy and is low ash count.. and plus that if you drive the rx7 like your supposed to do the carbon doesnt build up a lot anyways!
remember to get on it every now and then!
