Hey folks, what if someone proved that dry nitrogen filled tires didn't force small amounts of moisture and oxygen, into the tire at 100 psi, causing the steel belts to rust, weaken and blow out at freeway speeds? And, because we didn't force oxygen into the tires rubber compound, we slowed oxidation of the rubber so that tire life was extended by 2 years? (8 tires @ $650 per tire X 20% longer life = How much savings?)
Now the proof isn't there yet, but then how many of us put Aerospace 303 protectant @ $10 or $15 a bottle, on the tires to help stop UV rays? Where's your proof that it extends tire life? To quote Ned: "Real proof is long term study under controlled conditions, and I am not aware of any such studies for RV tires." Anybody have a 303 study they want to throw onto the table to prove it's value?
Anyone here wax their rig to make the paint last longer? Where's your proof that it works? Oh, anecdotal evidence again? I read in here where that wasn't really proof. Do you do it because you see the difference and you think it works better? Why does nitrogen in tires need scientific proof but wax doesn't?
Has someone got proof that changing your oil every year is better than every two years? I'm talking proof here, not what some salesman said. Shouldn't we demand proof that motorhome engines need to have the oil changed every year? Motorhomes are different than other vehicles, we should have proof that it's necessary for them before we change all that expensive oil. The contaminents in dirty oil are just a tiny percentage of the total oil volume, way less than 21%.
Hmmm, I wonder.
