buster, Please re-read the last portion of my post.

Synthetic 5W30's can hold up ok but 5W30 conventional oil should not even be allowed by law!!
Your rebutle preety much states what I said in the latter part of my post!
If anyone cares to take their LS1, Volvo SR60, S2000 on a road trip of 1500-3000 miles at HWY speeds with Tech 2000 5W30 conventional and then come talk to me about shearing out of grade that is fine. I have not seen a OTC conventional 5W30 with 1500 miles or more on it that has not sheard back to a 20wt. I also have not seen a 5w30 conventional oil that can last to the recomended 7500 mile change interval with out substaintal makeup oil. Even the group II+ base stocks like Chevron, Connoco and Pennsoil use have showed sever shearing in the 5W30 oil but not in the 10W30's.
Conventional OTC 5W30 simply does not provide the best protection for your vechile period! If you are not doing UOA and you have not tried other weights what basis do you have to make a judgement?
Buster, In an erlier post you recommened that a poster add a quart of 15W50 M1 to his 5W30 to reduce lead wear in his bearings you also advocated a 40 wt oil in the same post. Now here you are saying that viscosity is almost irelavant in reguards to wear. What happened to consistency? You can not have it both ways!
Either viscosity is important or it is meaningless. But it can not be relavent in one post then irrelavant in the next post!
