Ever since i changed my oil a couple days ago it seems that the truck is taking slightly longer to start up. Maybe half to a full second. A couple times i even let go of the key thinking it was started already. What could this be caused by?

 

More oil causing more crank case pressure and its taking the starter a couple more revolutions to get the motor spinning fast enough to fire...

 

did you put a heavier weight of oil in on accident maybe?

 

It was a different weight. I had asked my grandfather to pick some up for me, and i didn't check to see what kind it was.

 

VOILA!


not a big deal its just harder to start when its cold.

 

Awesome, i was getting worried about it for a second. Thanks guys.

 

i put in a little heaver oil and i'm having the same problem.

 

you guys are likely hurting your fuel economy
not sure if it will notice, but it has a negative effect

 

Really you should change back to the lighter weight oil. The thinner oil fits into the tighter tolerances in the motor better helping to maintain engine life.

 

what he said........... for the longest time i ran with 10W-30 in my 2.5, and didn't really have any trouble with it, then i went a little lighter with 5W-30 Mobil 1, and the truck seems to like that alot better
