My car starts pretty hard when it is cold out now-only when its cold not when over like 30 or 40-it starts up after a few seconds and makes a lil grinding noise.I have a brand new battery so its not that and i was thinking it was the oil. I am running 10w 30 now and just bought 5w30 today -will that help/fix it . I heard that should be it because the oil is 2 thick and cant get to the top of the block fast enough. is this true thanks and does anyone else have this and did it go away with the change

 

anyone on the oil thing? - does it make sense to switch to 5w30 -and will it help on startups? it is like 15 degrees today here

 

You certainly should switch the oil. Nissan recomends 5w30 year round. I don't think that would cause hard starting though.

The grinding noise thing sounds like you need to regrease your starter. There was a writeup on motorvate until it was destroyed by some type of worm. I don't know if frank has gotten it back up or not.

 

yea i thought it might be the starter or something but it only does it when it is cold out and not when it is kinda warm -i dunno what it is -i should b doing the oil 2morrow unless it is still snowing so i will let you know how it works out -has anyone every had this b4
