ix35 (Tucson LM) petrol and diesel engines need different oil specs. Read the filler cap and manual for the engine code on the plate.
After purchase, check every 500–800 km at first. City use ages oil faster; many shops use 7–10k km or yearly with a new filter. Rising level on a diesel can mean fuel dilution — that is urgent, not a free top-up.
Fast level drop, blue smoke, burnt smell, or puddles under the sump → seals, valve cover, turbo (boosted diesels), PCV, or bore/rings. Gearbox and transfer fluids are separate products. Keep a litre of the filled grade in the boot and save receipts.
