HA! I'm sure a few people around here will still insist on using 5w20.quote:
A friend of mine was at the SEMA show and said the Civic Si calls for a 5w-30 oil, not 5w-20.
Nice car but as someone has has already mentioned, too heavy, too ugly.
Ariel Atom has the same engine and transmission as the Civic SI, but with only 1003 lb to push around, it does 0-60 in 3.6 seconds.
There is also a 300hp supercharged version that did 0-100-0 in 10.88 seconds. That is quicker than a Mclaren F1. And it all started with a Civic engine.
