Most of my customers wouldn't know the difference in oils from 5/30 to "Mazola",
and back to anti freeze I can't keep the difference straight in my head either,
And don't even get me started on organic acids!
One would hope that if it were the main dealer the right product for the right vehicle would be the thing but in most of the dealers round my way they're staffed by non mechanics,
Same with my local European big store.
Best guess is that the big manufactures engine design people are the same kind of people that make chargers for mobile phones,
I have a large box full of the dam things and not one is remotely compatible with another.
Whitworth must be spinning around in his grave.
I agree with your complaint but all I can suggest is follow manufacturers specs,
And that probably requires manufacturers workshop manuals.
Which is what I use,
Rather than the industry standard book/reference which I find occasionally useful.
And as a business I keep all my paperwork so in the event of say cat failure from incorrect supply of oil I know exactly where my first call is going!
