Hi ... i have this Suzuki Jimny 1.3L, don't know if it's JLX model, but i think its a 2003 model and the top model that year. Automatic transmission. The problem is ... i lost my manual. Just want to know what the Engine Oil specs used for my vehicle. Is it the 20W-40 or 20W-50? My friend says its indicated in the manual, but i lost mine. Please help.
