DON'T CHANGE GEAR RATIO

Engine too weak to hold 60 mph on hwy. I used to have 94 Geo Tracker 4wd with 5 speed. It very weak for hill on highway. Need downshift to 4 gear at 4K rpm to stay GO on bridge.

Those engine can run at high rpm no problem. Just change oil with FULL synth 5w30 or 10w30.

I have mine up to 5K rpm for 5 miles due emergency. It got 26 mpg

I get 28 mpg MOST time at 60 mph but no job so I stay 52-55 mph it got 31 mpg.

You can improve mpg by fix rear door that where serious vacuum suction. Every-time I go on dirt road my rear window is cover dirt INSTANT.

Now I am try buy 1998 Suzuki Sidekick Sport with 1.8L bigger motor this week for summer daily driving.
