What weight oil did you end up buying?
For track use, I would never run 10w-30. I even run 20-50 synthetic in my daily driver. These motors appreciate the thick oils, and at high operating temps (track use), the heavier weight will make a difference in the long run.
I doubt you'll notice a better running and easier starting motor by using the oil just by switching oils.
Amsoil is a great oil to be using, but at the rate I change my oil (normal, at 3000 miles), I can't justify spending that much per quart when I know it will not be the saving grace if I do have a problem. Clean oil is key, even if it isn't synthetic.

20w-50 is too thick for a stock clearanced motor...but if you are going be running pro-longed amount of time at the track with high oil temps (<250F and above) that may be a consideration. I wouldn't DD it though as their are more drawbacks to running too thick of an oil...especially in this climate. A GOOD 10w-30 will not shear at high temps and maintain viscosity which will trump any need for something thicker.
I guess mentioning that my motor is built would be the key reason I run that thick of oil in my daily. But at the track, I would still argue that 10w-30 may be too thin, even for a stock motor. I think a 10w-40 would be a good balance of keeping the engine temperature down and viscosity.
I use Royal Purple because its more readily available at the auto parts store I like to go to, the price isn't too bad, and they have a decent reputation.

So in my previouse post where boom29 runs 10W30 for 2 race seasons now, 20 min time attack sessions at WOT speeds up to 130,,, Dominator 10W30 has been working fenomenal in his case, there has been no ned to run 20W50 in his case, 50 oil has its place and its not the case of the OP in here, he and you will just slowly starve the engine.
you see thats the best of proofs right then a race car running a product and proving it works or not.
Oil pasages are designed to be so big and using thicker oil will just prive the critical parts of the engine to be lubricated.
So in other words all the testing that has gone into synthetics was in vain, ;arge auto makers like ford, GM, Chevrolet, toyota ect, reccomend synthetics because they want the consumer to drain at 7500 instead of the conventional 3K,,,
now go and use some petrol oil on a turbo charged car and i will keep using synthetic and then lets have this conversation again in a few years down the road,,, you might come back with a different mind set

clean oil is not the key that is missleading to others, an oil with a good additive package is the key oil with the right amount of anti wear metal additives, and detergents, an oil that is capable of handling the abuse heat puts on them from a turbo and a cast iron block in the case of the 4G engine.
in the case of oils you get what you pay for !

^ I tend to agree. Dino oil can be improved upon... Hence the synthetics.
Also I dont believe that any of the oil analysis of a fairly stock car with the occasional track use has shown that the 3K change interval is mandatory.
If the argument goes that Amsoil is too expensive, yet you change it (unneccessarily) every 3K, then your argument is invalid. You would be saving money by changing your oil when you NEED to, aka ~5-7K miles depending on usage and going with a higher quality oil.
You can get the info you need to send your oil out for analysis at Bob is the oil guy.

i see your point however we have learned otherwise.
I love my amsoil products. But they are difficult to come by - thats the only issue i have with them. Hey Apagan, did u happen to get a tracking number or do u think its going to take longer to get them here or what? I gotta know if i am AutoXing this weekend!
edit wooo hoo its going to make it here tomorrow. This is good. I can make the autoX this weekend. Anyway thanks mang.

TTP, is another big shop who uses it and has great outcome out of it,,, when dealing with picky customers one must deliver the best of the best.
You know what would be great? If we could have a conversation in the NW section without others that we may not happen to give a crap about coming in and pushing their biased opinions.
At the very least, please keep conversations that could be in PM in actual PM. And try not to bash, even if politely, on our local buddies. Thanks.

I just stated facts and racing data where it pertainned, opinions have no basis, data and real life testing do have a basis on where they stand, i am trying to correct the statements made to educate .
not sure whats wrong with that.
now we must continue on topic !
