Re: dipstick read & "oil high" notice in the odometer in v-6 engine
Fieros originally held only three quarts but Americans usually run two quarts low and engines failed. rod went through the forward side of the block, oil sprayed on the catalytic converter, and car went up in toxic smoke.
GM responded with a bigger oil filter, remarked dipstick, a shield over the CC, and a sticker on the hood.
When racing I always ran a quart over full to account for the oil in the rockers. Isn't too full until starts dragging on the crank & gets whipped into foam (can see on dipstick).
