save camshaft from early death

In recent months i have taltked with people about cams going bad and wiping out the valve trane due to the lack of zddp. Zddp has been decreased over the past 3 year and now there is not enough in sm API rated oil i have been using it in race motors in large quanitys for years. The oil co have reacently lowered it zddp in Diesel engines by about 30% we ar now seeing more and more cars anf trucks coming in with cam problems. I have spent alot of time look in to the least expensive way to save money and not kill my cam. You can get the strongest zddp from www.zddpus.com they have a good tech brife section that will explane just about every thing i could think of about these new oil problems. I have talked with people that say i have never had a problem it seems not long after that they call and have a tick that cant be fix and its now to late!! when i order on the east coast it takes 2 to 3 work days after orderd to show up every thing over 1 bottle shipped for FREE. Zddp is recomended for all cars and gas engines 1990 and older some over head cams like vw audi mini copper therew 2010. All Diesel engines 2007 and older. I hope this can help some one so they dont damage their engine like i did it cost me $2000.00
