How long ago? When I checked some Quaker State I'd had >10-15 years, the bottom .5" of the (plastic, screwtop) containers was wax. I didn't use it.

1. Look in your owners manual
2. Select the recommended weight for your climate range (likely 20W50)
3. Identify locally available oils in that weight
4. Figure out which of the locally available oils has >1100ppm of ZDDP in it
The tricky part is step 4 - most oil manufacturers don't publish that info so you'll likely have to phone their technical helpline.
Also be aware that formulations differ by country - so Mobil 15W50 may not have the same level of Zinc in it in Ireland as it does in the US due to differing standards regionally (API vs. ACEA vs. JASO etc.), as well as regional fuel differences (levels of sulphur, available octanes etc)

If you use Amsoil..dont use too much.
I read somewhere it soaks into the metal, and not only makes everything lightweight, but entirely friction proof as well.
Only takes a few quarts.
