Will say NAPA has been my friend for lots of things appropriate. But if it is Euro of any type then you better know it is correct. Very rare I ever returned parts to Napa. A few times only and never an issue with refund.
And keep in mind there are a bunch of NAPA stores in very rural areas. They provide big services to all the farmers and ranchers far from the cities.
I still get most my lubricants and supplies there.
