Why Different Fuel Mileage for Civic VXs

[LarryJ]

Hello Everyone,

I'm new here, nice to meetcha..so to speak.

Like many other people lately, I've been researching the best fuel mileage cars and wouldn't you know it, I've decidede I need an early to mid-1990s Civic . I noticed that Mpgomatic.com lists two different fuel mileages for what appears to be the same vehicle. For example, in 1990 there are two mileage quotes for a CRX HF, both with 1.5L M5 manual trans; one is 49/52, the other 43/49. What's up with that? Thanks.

CA & federal?

One of those has a shift indicator light (SIL) which lights up to tell you when to shift.

[R.I.D.E.]

shift indicator is federal.

Either federal vs CA or it's the revised EPA estimates. They changed how they calculate their estimates. The new method is more pessimistic / realistic to what you can expect to get.

Those would be the old EPA estimates.
