I got a million e-mails about SWEPCO and what a "paraffinic" base is.

An oil can be synthesized in one of two fashions... totally made from scratch using ester base stocks as Jet A/V oil is made..or...from conventional oil and then synthesized or changed using chemical processes. Parafinnic bases are SIMILIAR to a PAO product but not to an ester product. They generally are thus comparable to much of what the base-stocks of Amsoil; Royal Purple; Mobil-1 and Penzoil Platinum etc. offer in the way of basestock performance. Which is fine.

The question is what additives are in it?

Sounds like a lot of moly as it is a "slick oil" as some have suggested. That would be similar then to Royal Purple which has lots of moly and ZDDP as well. RP has been shown to reduce drag and increase HP by reducing friction. A lot of moly makes an oil act "weird" I am told if and when mixed with gasoline from blow-by. POA's mix with gas well and so do products with heavier ester bases such as Redline.

I personally like a balanced oil....heavy on the ZDDP...a solid base that can handle 450-500*F...good detergents like boron and calcium...a moderate dose of moly if any is fine...and good dispersant's as well.

I think redline as many of Bob's foks do as well has a very heavy detergent additive package which includes silicon and aluminum...along with a lot of moly... Some say RP has too much moly...it seems after much work that Amsoil Series 2000 and 3000 products and many of the Mobil products have the balance I am looking for.

I hear the guys at Sterling looked at how oils mix with gas in blown engines...I heard today they are still using Mobil-1.

Pick what you like..just be informed is my motto.

Synthetic in cases and conventional oil for internal combustion, land or sea.

I never run out of protection or money this way and I have excellent success.

Yes, Mobil 1

Pantera1

I dont use it in everything due to cost.. But synthetic is hands down better than fossil !

white scarab

Synthetic in motors, drives, transmissions, etc.
Amsoil all the way!!!!
Synthetic oil is used by NASA, military, racing, aircraft, etc.

The military switched to synthetics because their vehicles are in storage for long periods of time and the synthetics protect during storage better as the flim strength is retained for longer periods of time...plus doing frequent oil changes while in battle is rough.

I've been running Brad Penn oil in my 750 hp blower motors strictly because my engine builder recommended it. When running fresh oil (I change oil every 10 hrs) my oil pressure would be 50 psi at 4000 rpm, oil temp 220 degrees. after the oil had 7-8 hrs of hard running, my oil pressure would drop when the oil got hotter than 200 degrees. I'm sure the oil was breaking down as when I let it cool, the oil pressure would return to normal. I've not had the oil tested but I'm pretty sure this oil was all done at 10 hrs.

From reading Hydro's posts on Mobile 1, I decided to switch. I'm now running M1 15-50 and I'm just plain floored at the dramatic difference in oil pressure when oil temps rise. I just took a half hour run and held oil temps at 220 degrees, the Mobile one was a full 20 psi more oil pressure than what I was running before. Even at 230 degrees (before the cooler) oil pressure held steady at 70 psi @4000 rpm.

Mobile 1 rocks!!!!

I went from dino to M-1 15/50 and saw similar results, then switched to the v-twin 20/50 and saw an additional 10psi at hot idle.

V-Twin really rocks

Biggus

I was going to try the v-twin but I could not find it anywhere .

I'll try to order some for the next oil change.

How does M-1 handle fuel dilution?

I'm not qualified to answer that in any meaningful terms, however, M-1 has an unparalleled record with it's synthetic oils in racing applications, also v-twin is made for Harley's which are very bad about contaminating the oil with fuel, then overheating it.
