I saw this poking around some AZs looking for clearance. Is this appropiate to use in something "modern"? Post 1990 in my case. Was debating mixing with some 0w-20 but wasn't sure as it's listed specifically for classic cars...started wondering if I do more damage trying to save a buck.
I believe it's this here, for reference:

Edit: everything in our fleet calls for 5w-30. Saturn S-series, Cavalier, 2 Cobalts, Cruze (wouldn't put it in the Cruze for warranty reasons).
