Here's how I change my oil I change it and filter every 4-k miles. I know that the new synthetic is supposed to go way many more miles than that but honestly I don't care. I like it changed at 4-k and I know for sure it's not hurting anything and my Hemi Loves it. Those that will say I'm wasting money don't worry about it because I'm not worrying about it. I have the cleanest in Town Lol !
Auto and lubrication engineers seem to be uniform in their belief that today's top synthetic blends will go the distance of 10,000 miles,
depending on operating conditions. Since I do not have access to all of the lubricant engineering data, I am putting significant trust into those opinions. Besides, if I did experience a failure how would I prove it was oil related?
My exception to the policy of extended oil changes using the best blend of oil, I have more recently adopted a strategy of short engine oil filter changes. Oil formulas today are much more advanced than oils of a decade ago, but despite the ability to retain film strength and stay in grade much longer (yes, I know some additives will disperse more rapidly) engine oil still picks up contaminants. Hence my 5K filter changes.
