I'll probably go through and change the oil and filter (already got these) but what about the tranny fluid and gear oil? What weight do I need? I see that I need .8L or 45 oz of gear fluid, .1L or 4 oz of additive and also 3.8L or 4quarts of tranny fluid. Is this correct? Also the 22,500 mile service suggest changing the air filter and plugs. Which plugs are recommended by everyone ( I know I'll probably start a plug war). Is there anything else I should change while I'm at it? Possibly brake pads if it needs it. I'm thinking I might put a new battery in it like a red or yellow top possibly.
