i had motor replaced 3 yrs ago with new jasper motor because motor went bad due to bad oil pump/sending unit cant remember which. its been running great and always reliable since replacement was done. just added few quarts of oil last week and right after i had fluctuations in oil pressure from 40-60psi. today on ride home oil pressure fluctuated between 20-40psi and i had a rather hard time maintaining speed on cruise control it wanted to keep hitting 3000rpm to maintain speed and i had hard time getting past 70mph. i have no oil leaks and ive always had steady 60psi oil pressure for 3yrs since motor replacement. PLEASE HELP ASAP THANKS!!!! o there is also a burning oil smell that happens rarely

added a few quarts???? how many??? did the motor start making noise???

start with a manual check of oil pressure to verify if it is low.

it also sounds like you have other driveability issues but start here
