Ok, im US Navy stationed in England, and I bought my wife a 1993 Accord 2.0i as her daily beater (sorry, im hardcore Mopar so I dont know a lot about hondas, though I do try and learn as much about the enemy as possible) . It's UK spec (right hand drive) and has no owners manual. I need to change the oil, and refuse to take it to a dealer cause they like to totally rape people anyway and right now the exchange rate is around $2 to 1 British lb. I have no idea what kind of filter to get for this thing, or how much oil it takes. It has 130,000 miles on it so far and has been incredibly reliable (as all hondas seem to be) to its previous owners. Any one here have any clue as to whatI need to buy in the line of oil and filter?

 

Between 4 & 5 US quarts so you need to buy 5. I don't know if you can get away with 4 liters.

Purolator P(or PL)14459 (older, bigger)
Purolator P(or PL)14610 (newer, smaller)

Honda has retroactively called for the newer small filter for your older car as well. You can use either one.

 

Can you check the engine for the engine code stamped on it? it should be to the right of the exhaust manifold somewhere. that would be able to help wonders. But I agree it is likely between 4& 5 US quarts. Do they have auto parts stores like AutoZone in the UK? I've never been there so I don't know. In the US if you go to AutoZone (or any auto parts store) they have books near the oil filters that you can reference for the exact part number of the filter that matches your car
