And it would take you 12.01 years to realize the cost savings of that amount to overshadow the cost of a new engine (SHOULD that one be damaged, etc, etc.. That is using a generous amount of $1500 on the low side for a new engine/labor)
I know.. how likely to ruin your engine, but..
How much damage COULD it be doing?, over the course of 11.9 years?
Unless you expect your engine to last 12 + years, you wouldn't even begin to get back in the black. Your engine will die before that, and the 124.80 a YEAR you saved will be gone quicker than you can count.
