Re: LPG/CNG cheaper?

[<mail@xxxxxxxxxxxx>]

I've run every vehicle I've ever owned on a 5,000 mile schedule. Never had an engine problem, Knock on wood [sound of knuckles on forhead]! Concumer reports did a study in the 80's. Found that any oil change prior to 5,000 miles was changing out oil that was still fully functional, at 6,000 miles it begins to break down no matter how well it is filtered.
Again this was in the 80's and done with 80's oil technology and dino oil.
Your mileage may vary!
Oh, and none of the vehicles be they Nissan,Chevy,AMC, Ford burned any oil between changes.

>AMS oil recommends never changing if you run their dual filter system and synthetic. I was serious about never changing anything but the filter and topping off every 5K. If the oil is staying clean it won't hurt a thing. Synthetic doesn't break down like dino oil, and the additives aren't as important. Even running dino oil I'd consider the same, excpet maybe a 3-4K filter/top interval. You have none of the reasons oil is changed at short intervals!! That's why EFI and computer control brought manufacturer recommendations up to 5K-7.5K average now -- less unburned fuel and carbon in the oil. If the oil change shops weren't so greedy they'd stop advising 3K oil changes -- that's 1960s technology!!
