I've been suggested by Crane to run Valvoline VRI or my favorite conventional plus some zinc additive since I'm using one of their cams.  They told me VRI to break it in for sure unless I wanna buy that high dollar Joe Gibbs oil, but I have no clue where to get it.

wow! i cant believe no one has said Mobil 1!

 Like I said I use to use mobil one, (What I should have said I used to Buy mobil one) Still do use it.  I still have three gallons in stock that I bought 8 years ago I use it in my elcamino only. I buy the Penns Plat Now because it's better and cheaper, besides that EX pres doesn't own part in Pennsoil.

Is there any actual info somewhere that can either prove or dismiss the myth of it being bad for flat tappet engines? I have been looking around but all i can come up with is speculations and people who 'heard' it was bad. Anyone know if there is actually any real truth behind this?

According to question number 8 under motor oils with the link you provided, it must be a total myth. The 10W-30 AMSoil that i want to use is 100% synthetic, and that says that it's for use with any engine. And that is a reputable company so i would trust them.

[choptop]

As a dealer for Amsoil, I have to say I have been more than impressed with their products and service. Alot of people think they have to run the manufacturers oil and filters or it voids the warranty of their vehicles. Harley is the worst. I can tell you this, if any manufacturer tells you you have to run their oil and running Amsoil will void the warranty, tell your local Amsoil dealer, and it will get taken care of. If the warranty requires only the manufacturers oil, they need to provide it free of charge. Amsoil stands by their product, and state if your engine fails due to their product, they will replace it/repair it.

I run AMsoil in my Harley over the HD oil. It's just a personal preference. The bottom line is this. If your engine is broken in and well maintained without any seriously aggressive camshaft profiles, run Walmart oil if you want. Take my Jeep for example. It has 300,000 + original miles on it using the cheapest crap that I have. I just replaced the rear main seal and oil pan gasket on it finally the other day and when I pulled the main bearing cap down it looked like it had 3,000 miles on it. The best thing to do with modern oils in a high performance situation is retrofit to a roller cam. If you can't afford it and are concerned about premature cam wear Rotella is the most cost effective good oil you run that I am aware of. I wiped my BBC flat cam from using modern conventional oils mainly due to prolonged sitting and lack of lubrication on start up. Now that is rollerized I'm not worried about it or I would have gone to a prelube system.

I ran the Rotella T 15/40 on my 81 3/4 ton when the 350 was in it for 275,000 miles. When the engine was tore down, it was clean and did not have much cylinder wear suprisingly. But I am picky, my oil was changed every 3000 miles on the dot and used A/C Delco filters exclusively. More about maintenance than type of oil I believe.

Chop top, we did an expiriment and cut open a bunch of oil filters a few years ago and the AC Delco filters were the worst. I have one cut open in my classroom still. The napa gold brand filter was way better.

Wow, never heard that before. Luckily change doesnt bother me. I have run Hastings, Baldwin, and Wix in the past as well, plus I can get the Wix filters through Amsoil.. How do they measure up? I was told the three were made by the same people, and I think the NAPA gold was too.

napa gold is actually a WIX filter, and is deffinitely the filter of choice
and i agree with chop top on the being libral with your oil changes, with the race bikes i look at a oil change every 5 hours of riding, +- 1 hour, and i can get this 250cc 41.3hp 13:1 comp engine keeping cross hatchings after 4 years of abuse.
and like vile said you can run the cheap stuff, but its about knowing when your oil is A)breaking down and B) time to change it

Well if you like bobistheoilguy and believe what he has to say, he will say to go with either puralator or motorcraft. The only thing he has to say about puralator is that it may filter too much, causing a slow down in the oil flow. He also says that you got two options when it comes to what kind of oil filter you want. Provided its a good and decent brand, that is. He say you either go for flow (performance) or higher filtration. There is a lot of different opinions out there though, i just tend to try to find someone like him who has done extensive research into the subject. I would never trust Fram, STP, Microguard, or any of those el-cheapos. However there are some out there that are expensive, that may just be full of hot air. For example i have no idea how good the K&N brand oil filter is, but they cost as though they were the best. For example you can get a Wix for 6 bucks but the same K&N is 13 bucks. At least i think. Been a while since i bought this stuff since i just got back into these old trucks fairly recently.

i meant i use the chevron oil 10w-40 in a blue bottle http://shop.oreillyauto.com/ProductDetail.aspx?MfrCode=CHV&MfrPartNumber=10W40.  i actually get it in one large bottle rather than five separate containers so it is really easy to use.  what i have found, however, is that it does collect water after a while, it turns black and becomes a sludge substance.  i use a bosch filter.
