This is from the Schaeffer Oil thread - didnt want to hijack the thread so thought Id ask it here....

The 9000 series is considered synthetic although it is still made with PAO(group 4) and hydrocraked bases(group 3-petroleum). Still a good product but made with some group 3 so it is a little cheaper. That info was right on their site. (I applaud them for putting this info on there. Many companies try and hide the fact it may not be a group 4 or 5 product and just call is synthetic.) Just wanted to be sure we were comparing apples to apples.
AMSOIL is made in Superior, WI....another American made

So whats the difference between a Group 4 and Group 5 synthetic? What constitutes a Group 5 synthetic?

Thanks.

Good question. Five doesn't necessarily mean better. The 4 and 5's are both products that are man made and not "extracted" from petroleum.
Esters, glycols and silicone are a few that are classified as Group 5. Vegetable oil is also classified as group 5....an example of a less than desirable base stock.
Not sure of the exact difference between 4 and 5 but must be strictly related to chemical structure and not its lubricating properties.
When it comes to a synthetic lubricant and whether is is composed of group 3, 4, or 5, the 4's and 5's are a chemically made substitute for a naturally occuring product. It can be manuipulated to arrive at a substance with the desired properties the maker is looking for. It also eliminates some of the "undesireable" properties of a petroleum based or refined products like paraffin and other contaminants or the wide range of molecular size particles you find. Synthetics can be made more uniform which also contributes to some of its propterties.

Sorry for the long winded answer. Appreciate the opportunity to address it.

Group IV is PAO. Group V is everything else, In the diesel world ester based.
