ACR oil

[Cobraken]

When I bought my ACR the Viper Tech said the ACR had a greater oil capacity than the stock Viper. Seem to remember reading @ least 1 road test mentioning same thing. Owner's manual does not draw a distinction. ???

The 99's are the same. The later years have the same pan but with baffles to prevent the pick-up from going dry under braking and cornering. I think the capacity was the same.

Start by filling with 8 quarts, top off until you hit your mark. You might end up with 10/11 but this is the safe route.

2000 ~ 2002 had 10 quart pans, better windage tray and no baffles, ACR or not. <2000 GENII's had 8 quart pans, not as effective windage tray and no baffles.

Confusion caused by ACR's having a special oil filter adaptor that provides full volume oil cooling, while non ACR's have a pressure valve that limits oil cooler flow under low pressure conditions like idling. This is in support of A/C performance in traffic conditions. ACR adaptors provide more cooling and slightly higher pressures as the pump doesn't have to offset the pressure valve. Both the pan upgrade and the ACR adaptor are backwards compatible to any GEN II. ACR adaptors are not recommended for winter use as they'll overcool the oil. I have upgraded my 1996 to the better pan & windage tray but not the ACR adaptor as I do use the car on clear cold days and enjoy the already weak A/C on hot summer ones.

Given the oil cooler and lines, the longer you drain the more you'll add on refill. On refill, I get close and then wait until morning to do my final top off.
