I did some searching, and i coudlent find a direct answer to my question which is in my '99 TL, would you guys recommend using Mobil 1 0w30? should i use 0w20? or 5w20 or the standard 10w30? I know the 02-03 they use synthetic, but the dealer uses regular 10w30 in '99-'01s. So i picked up 5 quarts of 0w30 full synthetic... should i take it back? remember, its a '99 and ive been running 10w30 in there for 63,000 miles....

 

in my 99 tl. in fl with the heat it basically becomes 10w20. i also change it every 3,000 or less! fluids break down and get dirty, especially w/ hard driving quicker than normal, syn incl. same for the tranny! every 5,000 or sooner w/ honda z tranny! depending on wether or not i hit the track, or a long drive in a short time frame, ie: fl to ny and back! i don't mind spending the extra$. my whip is a huge investment!!! and she loves it
