To preface, this thread is not meant to question the necessity for warming up an engine properly before running it at modest speeds, but does anyone feel like the 6mt is incredibly sluggish when the engine is not warmed up. I've driven many other vehicles (with various engine sizes and compression ratios) that respond much much more when not warmed up (even in 70 degrees plus weather). Can't recall what oil I am using (dealer filled) but should I be going to something less viscous?

 

the VQ motors have to warm up before the variable valve timing can be very effective. just like the toyota vvt-i setup that runs on engine temperature-- if it's not warmed up fully then the valve timing will be off. the oil really doesn't have as much effect unless you are running an extra heavy weight which i doubt you are. i hope this all helps

 

Seems to me too that the VQ runs very rich when cold, hence the poorer gas mileage in colder climates. A rich running motor will not perform well.

I thought there was something seriously wrong w/my G when I 1st drove it in the cold. scared me!!

 

Are you guys serious? That cold denser air will make 'em run like a champ. My 6MT seems to love the cold weather--when it actually rolls out of the garage

I usually give it a few to get up to temp before any kind of hard acceleration, but after that--oooooohhh yeah.
