Tips for any of my cars?

[Robin Hood]

I'm new here, just started browsing. I'm wondering what there is to do for any of my cars...

• 1977 GMC Sierra K25 400 SBC KN Filter with X-stream
• 2004 Ford Ranger 3.0L V6
• 2003 Nissan Sentra SE-R (NOT spec-v) 2.5L I-4
• Honda Civic EX 1.8L I-4 has a KN Filter

So yeah. Pretty much any idea's are appreciated.

Thanks.

IMO, focus on:
your driving technique
keeping tire pressures high
maintaining the cars well
driving slower overall

a (partial) grill-block should be the first mod to any car for FE. it's the one that you will actually see results from.

EOC(engine off coasting), if any are standard trannies, in addition to EH3's recommendations.

Nah, all are Auto.

I'll give a shot at going slow.
