[Shotimes] Oil and gas

[Mark Mucher]

A couple questions:
 
I've always used Mobil 1 5W-30 in my '89
 
My new '90 has always had Castrol GTX 5W-30
 
I'm thinking of trying one of the new high mileage oils (Max-Life, etc.) in
the '90
 
Any suggestions?
 
Also, does anyone see any problems running mid-grade fuel on a long, flat
interstate highway trip?  I've always used premium before...
 
Thanks,
 
Mark
