Uh oh, Here We Go Again!

There is no one base molecule.

Another type of base oil is made from refined and processed esters and is called Group V. Esters start life as fatty

acids in plants and animals, which are then chemically combined into esters, diesters, and polyesters. Your

vegetarian girlfriend should love that. Group V base stocks are the most expensive of all to produce. However, the

esters are polar molecules and have very significant solvent properties - an ester base oil all by itself will do a very

decent job of keeping your engine clean. So, people who are serious about making a superior oil will usually mix

some Group V oils into their base stock.

An example is Red Line oil:

We don't need to attack your personal knowledge, you do that so well for us. And watch out, your hand is gonna get tired from all that waving. Stick to jeeps and motors where you do appear to know something.

It would be funny if not so consistently inane.

From my post earlier: ..."Esters start life as fatty

From that link you just provided

......."In automotive applications, the first qualified synthetic crankcase motor oils were based entirely on esters and these products were quite successful when properly formulated. Esters have given way to PAOs in this application due to PAOs lower cost and their formulating similarities to mineral oil. Nevertheless, esters are nearly always used in combination with PAOs in full synthetic motor oils in order to balance the effect on seals, solubilize additives, reduce volatility, and improve energy efficiency through higher lubricity. The percentage of ester used in motor oils can vary anywhere from 5 to 25% depending upon the desired properties and the type of ester employed."

..."Summary

Esters are a broad and diverse family of synthetic lubricant basestocks which can be custom designed to meet specific physical and performance properties. The inherent polarity of esters improves their performance in lubrication by reducing volatility, increasing lubricity, providing cleaner operation, and making the products biodegradable. The wide range of available raw materials allow an ester designer to optimize a product over numerous variables in order to maximize the performance and value to the client. They may be used alone in very high temperature applications for optimum performance, or blended with PAOs or other synthetic basestocks where their complementary properties improve the balance of the finished lubricant. Esters have been used in synthetic lubricants for more than 50 years and continue to grow as the drive for efficiency make operating environments more severe. Because of the complexity involved in the designing, selecting, and blending of an ester basestock, the choice of the optimum ester should be left to a qualified ester engineer who can better balance the desired properties."

"Oil changes from petroleum to bio-based oils also show very significant reductions in tailpipe exhaust emissions (Fig. 6). In a petroleum to petroleum cycle (Pet-pet), hydrocarbons (HC), carbon monoxide (CO), and nitrous oxides (NOx) all show increases over the 6,500 km test period. Conversion from petroleum to a bio-based motor oil (pet-can) has an immediate and dramatic decrease in exhaust emissions. Continued use of the bio-oil continued to decrease HC production while giving no additional losses to the already depressed CO and NOx production."

It'll never see the light of day, the petroleum lobby will make sure it's made illegal.

Bill, you don't have your gas station, why do you remain a shill for the petroleum industry?
