Why we built MyEngineOil

The information needed to buy a bottle of engine oil is scattered across handbooks, forum threads and retailer lookup tools that quietly steer you towards their own stock. Getting it wrong is expensive, and the mistake usually shows up thousands of miles later.

We aggregate manufacturer service documentation into one lookup, present the grade, approvals, capacity and interval in plain English, and show every source we used.

The lookup is free and will stay free. It is funded by labelled product placements, which never affect the specification we show you.

How we handle corrections

If you can point to manufacturer documentation that contradicts something we publish, we will check it and update within a week. Where two sources disagree we publish the stricter requirement, because an over-specified oil is a waste of money and an under-specified one is a repair bill.

Data sources

Manufacturer service documentation

Workshop manuals and technical service bulletins, indexed by engine code rather than model name.

ACEA oil sequences

The European performance sequences that define the A/B, C and E classes referenced on every bottle.

API and ILSAC standards

American licensing standards, used for Japanese and Korean vehicles where no European approval exists.

OEM approval registers

Published lists of licensed oils from VW, BMW, Ford, GM, PSA and others, checked against product labelling.

Affiliate and sponsorship disclosure

Some product links earn us a commission and some placements are paid. Both are labelled. Neither changes the specification we publish for your engine. Read the full disclosure.
