like all oil treads, oil is something personal to most folks
some like"X" brand, some like GOOD brand name, some go as cheap as possible and some go as long as possible on changing oil
so all info here will/should be viewed with a grain of salt
many folks and even dealers/HONDA< seem to think, NOT running SYN oil is good for the first 100+ hours, allowing things to set in and such!
after that, seems everyone has there views again
as far as I am concerned, as long as oil is clean and meets spec's needed, if really doesn't mater as long as you change it when its needed
and I say NEEDED< not going by hours or miles
over work a engine, run it hard in dusty places, and oil changes should eb done sooner, and I don't care what oil brand your using!
I personally run Amsoil, and have in countless things since there first oil changes
but again that's MY personal picking
lots of folks like T 6 cause its available lots of places and for a great price most times
but the main key is and should be, just change it when it needs changing, don;t be trying to squeeze every pounce of time and use out of it!
oil is still cheaper than a new motor!
and as for OIL filters, again, many will have what they feel is best
I have used most brands, but tend to stick with OEM< NAPA, or like brand named one's
and its mostly due to I buy them in BULK< to get best prices and there sold close to me
the key where again, is put them in the RIGHT way, and change them when changing oil!
I am sure some of every brand have been BAD, but I never had one yet! of any name brand!
