With a plastic spoon! Also if you get them in plastic bottles, don't use a metal funnel. Need aluminum engine and oil pan or it will clog up everything, I think?

Well, I guess I would understand your humor much better if I'd know you personally. So, you make your wife a hard time, with your sense of humor AND your strange hobbies like using fuel & oil additives in her car...

Ah, yes - the carrier oils. It's very hard to dissolve additives in PAO's. Well, even "fully synthetic" oils use Group I oils as carrier oils... So much concerning "fully synthetic". And yes, M1 uses Group V oils.

Sorry, I still don't know what you mean with AN... Group V does not define Ester oils exclusively. Group V is defined as "unconventional oils". I do not know every synthetic oil on the market. Look at the Noack, if the Noack of an oil is below 8%, you can be rather sure that no group I oils are inside. But why are you afraid of a some Group I oil? It certainly does not hurt your engine.

So , we can see now that Mobil's AN fluids can even be used for blending mineral oils and have inherent high solvency .
Has anyone here ever switched to the Supersyn from mineral oil and found the oil got dirty rather quickley the first run on it ?
If I used minerals oils I would probably use one oil change interval during summer with Mobil Supersyn to get some minor but effective cleaning around the piston rings .
But back to the blending fluid . I would like to know which companies are using it in their oils . It's now sold in Europe too .
Nobody talks about seal combatibility which is way more important for an "every day" car application. Or is everybody doing racing here and at BITOG at the weekends? Who really needs esters? Not many engines do. Can esters hurt seals and elastomeres? Yes, they can. Where are the advantages for an every day car? I can't see them.
Did you know that some mineral oils use esters as pour point depressants and that many of the modern additives have components of alcohols that are esters and this includes zincs ? A consumer would be hard pressed to purchase a motor oil without some type of ester additive in todays world . The better oils that actually meet ACEA standards are engineered with compatability of seals . www.acea.de
These esters and derivitive additives actually condition seals and help keep them pliable . Diester can help eliminate bore polishing when the concoction is well formulated with the other detergent and dispersant additives .
I beleive more emphasis on the reduction of bore polishing should be noted on the boards . When you still see the honing marks upon inspection after 200 thousand miles you know the oil was formulated well . Mobil always used some ester and there have been many notes about the lack of cylinder wear when that oil was used for life .

At the time I wrote that entry, I was thinking more about pure ester oils. After that post I made some inquiries concerning esters, mentioned here in this forum in another thread. In fact, a 10 % ester content may even help you to pass a severe ACEA B5 engine test concerning piston cleanliness. Interesting enough it seems that a higher amount of ester will decrease the piston cleanliness.

Appox %s Magnatec uses say 20% ester in a mineral oil base. Silkolene uses 20% diester although perhaps a road/track track oil. Above that % the oils are really only for race purpuses with Motul 300V a 20% diester plus mix of PAO/ester and Redline an ester/PAO.
Magnatec appears to be only road oil that promotes esters for start up protection, the others being for protection at high temperatures. (M1 maybe ester or esterless! just states uses 3 Synthetics )
I've changed my opinion lately with RL after speaking with a guy from Butler Labs. I believe RL is an outstanding oil in severe driving conditions such as racing and an oil that maintains it's viscosity better then any other oil. It will also keep your engine more clean, due to the high Ester content. Not to mention, the small ppm wear differences we see in analysis reports are not always wear, especially with RL. It's a tough oil to evaluate, but the "experts" at BITOG say nothing but great thingsa bout Redline.
i love redline i use 3qts 10w30,1qt 10w40 and 1qt delvac 1 5w 40 for a high 30wt. 12.3 cts this is in my vic...in my expy and conti i use 4 qts redline 10w30 and 1 qt synergyn 3w30 and 1 qt delvac 1 5w40
