WAIT WAIT WAIT......... Are you guys overdoing this "3 months or 3,000 miles" Scenario?
Thats typically what is recomended for EVERY car out on the streets, but most Vipers are NOT daily drivers. Think about it... most people drive to work 5 days a week and sit in traffic QUITE OFTEN, so many statistics/tests would be conducted under this type situations.
So, if you only drive 5 miles to work each day, but you sit in HOT traffic each day for about 25 minutes, to and from work, then your engine is working hard, right? The deal is, you will not accumulate very many miles on your "odometer" but your engine doesn't care... it has busted it's ass in traffic (breaking down oil molecules).
Result, you should change your oil in 3 months, because your engine has worked hard in those last 3 months, but you probably will not see 3,000 mile intervals very often in that car because you only drive a few miles a day.
For my viper that sits in the garage and only has seen about 1,000 miles on the odometer since the begining of this year, why on earth would I be changing my oil? Pouring oil in my car and letting it sit in the garage for 3 months.... would not mean "oops, 3 months is over, better change the oil", although my car never moved out of the garage. The oil is still fine in there. Maybe not as fresh as the day I opened it, but it's not like it has broken itself down and is no longer any good.
I think the whole 3,000 mile thing applies to EVERYBODY, but the 3 month time line applies more to those who sit in traffic, because your engine is running and working hard. Thats what requires new, fresh oil, engine work, not car miles.
To simplify this even more.....
3,000 miles OR 3 months on your ENGINE, not so much on your odometer.
How about this... Lets compare 2 coworkers.
Employee "A" leaves at 5:00pm each day from work and sits in "bumber to bumber traffic", A/C cranking and inches his way home, taking an hour to go 5 miles each day.
Employee "B" leaves work at 7:00pm when there is no traffic on the road whatsoever and he goes the same distance in only 5 minutes.
Both cars traveled the same distance, but who do you think should change his oil in more frequient intervals (this would be every 3 months)? That would be employee "A" since he had much more wear and tear on his engine, breaking down the oil's viscosity more.
does this make sense?
