i got a LS a1 and usually use 5w-30 full syn.. i just changed it and use 10w30 full syn because winter is coming.. and it feels like i loss power litierly.. i know oil doesnt help you gain power or what not.. but i can feel that accel like it use too.. i was thinking bout flushing it back out and goin back to 10w-30.. any ideas on what i should do...

 

why did you cjange to a thicker oil for colder weather? you have it backwards bro. run thivker oil in summer and thinner in the winter. the reason it feels "slow" is the oil takes longer to heat up sloweing the internal parts just a small amount. switch back to 5w-30

 

yeah talk to a friend of my and told me i had it backwards too.. haha dumb on me.. thanks for the input
