Most people at my work don't change their own oil, they just go to a local garage to get their car "serviced", which is the code word for an expensive oil change. Yet when I talk to these same local garage / mechanic shops, they only ever stock three bulk oil: 5W30 SN semi-syn, 10W40 semi-syn A3/B4 and a mineral 15W-40 HDEO for the diesels.
My oil stash ....errrr....investment portfolio offers a better selection than this.
Also many engines that appear in north America also appear in Australia. The Buick 3.8L V6 is a good example. In NA they appear to recommend 5W-30 or 10W-30 yet in Australia the same engine is recommended to use 15W-40 or 20W-50. So in Australia if you stick to 30 or 40 grade oil, you have pretty much everything covered.
BTW I was speaking to the local Jeep dealer about the new Patriot (fully imported and the same one you get in the USA) and I asked him what oil to use, he said the recommend grade was 5W-40. What would they use in the same engine in the USA ? 5W-20?
Anyway I think most engines are less fussy on oil than the average BITOG member.
Me ? I'm homing in on 5W-30 or 10W-30 A3/B4 as my do all grade for everything.
