Mobil One bad for Type 4's? Options

[ChrisReale]

I did a search over at pelican, and read that one engine builder "hates" mobil one, and it is not good for the type4. I use it, and I know a lot of others who use it. I'll throw some poop in the pot...

Is it bad for our four bangers? Why?

Wayyyy back in High School. I had two years with a professional motorcycle mechanic. He ingrained in my brain about oil. "Oil is oil and there are types of oil.
Racing Oil, Multi Viscosity and bean oil. (two stroke oil). That same year. Wayyy back, an oil dude from Pennzoil came in to lecture us about oil and said the same thing. Just change it whenever it gets dirty. Since then I've tried to be a nut about buying the best oil I can afford and changing it as often as possible. Oil is blood for the engine, right?
I've seen a 63 Ford Galaxy with 250,000+ miles on the original engine. I asked the owner what his secret was. He said he changed the oil and filter every 2000 miles if it needed it or not. What kind of oil did he use?. Whatever he could find in Kragen's.
Lately have been hanging out with the Mopar Alley club here in San Jose. There is a school of thought about the new oil being sold with the sunburst label. It lacks the detergent needed to collect dirt from inside the engine. A owner of a nice Challenger has his 440 rebuild with all the bearings wiped out . He thought it was because if the 99cent stuff with the sunburst label during break in. Another member attended an Auto repair class at De Anza in cupertino, and harped about
Sunburst oil after seeing a 25000mile. Caddy 32Valve Norstar V8. Full of sludge and carbon. I know it sounds like (IMG:style_emoticons/default/bs.gif) but, I can only tell what I know. Since then, I run Redline in my 914 and change it myself whenever it gets dirty or 2000miles. The truck gets the cheep stuff at the Grease Monkey and changed every 2000miles.
