I've used this system in all my old musclecars, BMW's, Toyotas, etc etc since 1980 when I started driving. NEVER had a single oil induced failure in any vehicle.

Anyone who tells you that you need to change the oil more frequently is just spending your money. Frankly, I probably don;t need to change it that frequently, but like I said, its a no brainer way to track on the odometer.

HOWEVER...I do check the oil every 2 weeks or so...checking on fill ups is not overkill, I would check at leaast every other fillup at a minimum.
