Most of the mid-sized business jets have a range between 3,000 and 4,000+ nm. Compare this to 3,100 nm for the 737-800 and 4,400 for the 757 and they seem pretty comparable to me. The smaller business jets align with the smaller airliners and likewise for the high side.
on October 7, 2013. Regular performance of an engine flush is not only safe, but it is a required part of regular engine maintenance, like an oil change, that must be performed in order to ensure a long life for your carâs engine. Prevent Thermal Breakdown.
First buy a can of flush to put in your engine oil. then run your engine for a few days to get hot and breakdown the sludge and varnish inside the engine. Change the engine oi â¦ l while it is hot and refill with good quality oil. I always use castrol synthetic as a personal preference.hat happens is the flush itself doesn't ruin your engine the debre in your engine does. Everyone that has a problem after one flush is due to the engine is so nasty on the inside gunk disolves everything, but it is not drained out the oil pan.
