Sorry for the dumb question, but at what point are these necessary and why arenít they more prevalent? Thanks

Accumulators provide extra lubrication. You can get them in 1, 2, or 3 quart capacities. Used in conjunction with either a ball valve or an electric solinoid you can prelube your engine prior to starting. Additionally, leaving it open during the day, you can have added capacity when your have a pan with limited capacity or an engine that doesn't return the oil back to the pan quickly.

If I remember correctly Olds engines have a poor return system and keep a lot of oil in the top half, thus sucking the pan dry after a long hard run and then causing possible bearing damage. Most engines will keep a fair amount of oil in the top half, especially the cylinder heads.

If you use the accumulator for prelube only you need to remember to close the valve after the engne has run for several minutes to keep the added capacity and max. oil pressure to push the oil thru the system again. Using an electric solinoid you can close the system prior to shutting the engine off at the end of the day and have prelube oil for your next startup.

Some drag racers will run an accumulator to run less oil in the pan to reduce windage, less wasted HP during the run, counting on the oil in the accmulator to make up the difference.
