I just had the oil changed for the car and I didn't know what kind of oil was used before and i just put regular oil in. IT SEEMS THAT THE CAR ACCELERATES HARDER AND WHEN ACCELERATE FROM 0 TO 30 MILES, THE RPM'S ARE HIGH THEN EVERYTHING IT'S NORMAL...I WONDER CAN WRONG ENGINE OIL CAN MAKE MY CAR SLOW AND GIVE IT A LOT OF TROUBLE ACCELERATING FROM STOP OR MAYBE IT'S A PROBLEM WITH THE GEAR BOX ??

 

Watch Your Posting threads..you had this in the Sights and Sounds forum Not quite for that area..I moved you over to here..

Thanks for posting..now you should get an answer...

 

What weight oil did you use? if you used a heaver weight oil it could crank slower in the cold. At 99,000 the clearance for the rods and mains bearing are mostly likely looser than new anyway. I don’t think you have a problem from the oil change until you went with something really thick like 50W .
