Some cars are beginning to be equipped with electric supplemental oil pumps. These can prime the engines before starting. But most cars today, like the Camry, still use the older mechanical driven pumps tied to RPMs that do not generate more than 4-8 PSI during idle. ========
Here's an interesting new pre-oiler from Amsoil.

Independent studies have concluded that engine wear during start-up is a major concern. Even though engine components remain dry for only a short period of time at ignition, when this circumstance is multiplied by the
400 to 600 dry starts a year by the average motorist, the potential for harmful metal-on-metal contact and significant wear is great.The AMS-Oiler? is an oil pre-charger that puts an end to dry-engine starting. Typically, an engine that sits idle for even a short period of time will operate relatively dry upon starting before oil is able to fully lubricate the system. In fact, the automotive industry estimates that up to 50 percent of engine bearing wear occurs during the starting process. Indeed, the superiority of AMSOIL motor oils minimizes start-up wear by clinging to the metal surfaces, but even more can be done to concentrate the oil on the critical wear areas in an engine. With the AMS-Oiler in place, 160 cubic centimeters of oil is injected directly on the engine bearings and other wear sensitive surfaces upon turning of the key, giving instant protection to vital engine components.
The AMS-Oiler? outperforms gas and air charge systems. When the ignition key is turned to the on position, an audible alarm sounds while a
12-volt DC solenoid initiates the AMS-Oiler's operation. When the oil delivery process is complete, the alarm ceases and the operator can start the engine. The engine can be started at any time without damage to the AMS-Oiler?, however, the AMS-Oiler? is recharged by the pressure generated by the engine's oil pump. Complete recharge is accomplished within 40 seconds. The absence of a gas or air charge eliminates the possibility of cross-contamination of dirty gas or air with the engine oil, keeping the oil pure and performing optimally. The design of the AMS-Oiler? reservoir also protects the unit from ambient temperature fluctuations.Specially crafted by AMSOIL technicians, the AMS-Oiler? is the culmination of extensive research and development. ?Our products are exceptional when it comes to reducing wear during operation,? said Technical Director Dave Anderson. ?The weakest link in the chain, however, was still during startup. With the AMS-Oiler?, we?re closing that last gap.?
With an extremely rugged chrome plated hi-grade carbon steel reservoir and anodized aluminum base, the AMS-Oiler? is crafted to withstand severe service and to perform reliably in any personal, commercial or industrial application.
Unlike other pre-charger systems, the AMS-Oiler? has no bulky moving parts which need maintenance and does not rely on pressurized gas to function. The AMS-Oiler? is a self contained, streamlined unit that has a mechanical life cycle exceeding one million engine starts, with no maintenance required. The AMS-Oiler? is self-lubricating with an integrated overpressure protection device that protects units from retaining pressures in excess of 90 p.s.i.
In order to meet consumers? needs, AMSOIL has designed two AMS-Oiler? models to cover all applications. The first model is crafted to attach directly to the AMSOIL Dual-Remote and Dual-Guard By-Pass Filtration mounts, with the second model designed as a stand-alone system for all other engine applications up to 500 CID (cubic inch displacement)(8.2L). The AMS-Oiler? retro-fit applicability to the AMSOIL By-Pass filtration systems provides a convenient perch for quick installation. For non by-pass-equipped engines, the stand-alone AMS-Oiler? mounts easily at any angle to accommodate virtually every engine.
With the new AMS-Oiler?, AMSOIL continues to make lubrication history, with quality still the number one priority.
