MPG ??

[scoobyjwc]

Hello friends
As of recent, my 94/95 Tahoe has been EATING through gas. You can almost watch the needle drop when I accelerate.
Are there any tips or tricks, or maybe some affordable upgrades y'all could offer?
It's making my 45 minute commute very expensive.
Thank you in advance

Is it eating more gas now than before, or are you just noticing it more now, due to higher gas prices?

Upgrades? No. That’s a fantasy.

Repairs or maintenance, maybe, IF it’s not performing as it should. There’s insufficient information in your first post to give any meaningful feedback. How about some numbers and some history?

Cap/rotor, plugs/wires before you try to decide about anything else.Recheck timing. No easy upgrades on this vintage.

Also you posted in 2021 year spot, not GMT 400 section.
