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?

I don't think Mobile One is a bad oil in a healthy engine, regardless of age. But wisdom says that it will cause leaks in an older motor with tired seals... but bad? Naaa. Sounds like other issues at play with the gentleman's overheating.

Im not talking about the overheating issue, Im talking about Jake Raby saying it is good for 911 motors but not good for type 4's.

I dont agree. Everyone has their own preferences, and while he has done exhaustive research, I would not be willing to take his advise over an old school mechanic without seeing evidence, which he provided none in his statement. So, who has some info on this?

I'll let all of you in on a little secret:

The dyno is not the end all to all of our questions.. honestly.. it's not even close to real world. Its a controlled enviroment where HE (Jake) has total control over the enviroment. I do agree that Royal Purple works well (seen it myself on a chassis dyno pull).. which is what probably happened in Jakes case (Royal Purple sales reps GIVE it away to known dyno shops).

I also agree that Redline works... I also agree that Amzoil racing synthetic works well.

My experience with Mobil1 has shown me increases in MPG and HP in every single car I have ran it in (Trucks/Cars/Porsches.. Motorcycles.

Make your own decisions on this... I promise there isnt a "bad" name brand oil out there.

I am sure the guy is a competent engine builder but he makes some wild claims. I think I would take anything he says w/ a grain of salt. (IMG:style_emoticons/default/confused24.gif)

It's raining here for the first time since last year. We used to get 10-12" but the last couple of years it's been more like 8". El Nino or something?

Last time I spoke to jake he was switching all of his motors to synthetic...I think he prefers valvoline full syn (or royal purple) over mobile one...but I think thats just his preference....all I know is that he had me switch my motor over to synthetic and it ran about 10degrees cooler on average (oil temp that is).

If you have a new motor, I highly recomend it...and you can't really go wrong with any of the big names...

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.

Bingo. Change the oil.

Typical World of Outlaws SBC's last 4-6 races. The fastest guy out there gets 18-20 races out of his engines and people freak out. His secret... he changes the oil after EVERY session. He uses 99cent 7/11 oil.

I have seen Chevy trucks used for landscaping rack up 300k miles and all the guy did was dump oil in and change the filter (never changed the oil... just dumped in fresh when changing the filter..like a rock)

Me.. I'm lazy. I change my truck every 6-8k miles with Mobil1.. but I change the filter every 3-4k miles.

There may be some true issues with the various oils out there. Lately, I've been hearing about Castrol GTX, a brand I've always liked, causing pitting on 911 rocker arms. Some offroad guys running 911-powered buggies competetively discovered this and switched brands. The problem was apparently solved with a different oil.

I don't know much about the chemical composition of oils, so I can't sort this out as being valid evidence or just an unhappy coincidence. Can oil do this?

I would think it was a rocker arm issue being exposed by the Oil. Like replacement arms being made from different material...
