I have noticed the starburst on some oil products have "energy conserving" on the bottom of the symbol and some don't. Usually the least expensive oils have it omitted. Should I stay away from these oils??
Energy Conserving Symbol

I also have a question about that..in fact, I've been asking it for several years but never got an answer.. How is it that Supertch HM is able to create an "energy conserving" HM oil and Mobil Clean HM is also the same, yet all others are not?

Do you mean the Starburst symbol or the Donut symbol?
The Donut symbol will show "Energy Conserving" in the bottom ring of the symbol ONLY if the oil was tested and passes their fuel efficiency requirements. (See http://www.api.org/aboutoilgas/motoroil/api-quality-marks.cfm) Higher viscosity oils generally do not pass the test.
Energy conserving is implicit in the Starburst symbol as passing the fuel efficiency test is a requirement for certification.

I am politically incorrectly opposed to starburst/energy conserving, and also like the fact that oils without starburst are (all else equal), more robust.
Lack of starburst is not problem so long as you buy reputable firm's oil, like Maxlife! Won't find starburst on anything thicker than 30 weight anyway.

I was referring to the "donut" on some oils not having "energy conserving" listed. I had the donut and the starburst mixed up. I'm new.
You'll find the EC label on most 30W and thinner oils which may help with gas mileage because of less drag and perhaps friction reducing additives....Most 10W40's and up won't have the label...
Maxlife has no donut either. Great oil. Donut not necessary. My favorite oil criteria is ACEA A3, which is usually 10w40 and up , but some 30 wt synthetics have it. Means pretty robust HT/HS viscosity (at least 3.5 cSt).

High HT/HS is for sissies!! REAL MEN run the edge ..or boundary ..of the envelope ..so to speak.

I've got your energy conserving RIGHT HERE!

I have some boundary conditions for ya: Try some of that SA/SB rated stuff at your local gas and convenience store. I hear it has cutting edge low additives (cutting edge as in cutting oil). Take a real man, perhaps even a redneck, to run some of that stuff.
