On a 2001 C-5 Vette, there is an on-board computer that monitors "oil life remaining". Let me preface my question and rule out "opinions", PLEASE, just the facts, just the TRUTH ... !
What is the percentage of "oil life remaining" that the oil should be changed at ? I've been changing it at around 45% and that gets me about 3500 miles or so. I've come to believe that that is way too soon and I am simply throwing my money away. What does GM, or a very knowledgeable Corvette Engineer say ???
How does 10 % remaining sound ? Isn't that the purpose of the computer monitor ? And what about changing the filter in between oil changes ??? Is there a truly BEST oil filter for this car ?
THANKS in advance,
Richard

Try asking the guys in the C5 General Discussion section over at www.corvetteforum.com. They know their stuff over there.

The percentage indicator runs from 100 to 0, every 7500 miles, so you are changing the oil every 3500 miles..half way, but it really depends on how long it is between changes and how the car is used.. If you drive a none stop commute to work, like 60miles round trip, the oil is at a steady flow & pressure, which is better than city mileage, with lots of stops, oil pressure jumps up and down and less circulation..In other words go to the 10 % mark if highway, but not over 3 months, and for city -50%, but you need to remember to use the recommended oil for your vehicle and do not change brands-due to different makers, use different detergents in the oil..Also a factor, if the automaker thought the engine would fail-due to changing the oil by indicator, then they you have set the indicator different..Hope this helps..

the chevy on board computer monitors it down to a point where it will notify you with a - CHANGE ENGINE OIL message. After which it is recommended that you change the oil within the next 600 miles. The computer doesn't use mileage to do its calculations. It uses engine revolutions and engine temperature. This has proven to be much more efficient than just every 3,000 miles. I usually change oil about every 5,500 miles +/-. Your cars user manual might have info on the computer. Hope this helps. Peace out.

The oil monitors engine rpm, distance, temp, etc etc to determine when to change it.... and it is pretty good... (seen oil analysis's of regular pennzoil, changed when the monitor said so. over 12,000 miles on that oil, did fantastic, low wear, etc)
Fram is cheaply made, overpriced junk, feel free to cut one open and compare with wix's..... stay away, keep with oem, wix or purolator...

Every 3000 miles is the standard.
I'd stick with that.
Especialy with that car. $$$
ADDED:
Filter too. EVERY oil change. Penzoil, Fram, OEM .....any good oil and filter.
