2001 - 2004 Ford Ranger 4.0L QUESTION.... - Ford Forums

01-28-2006, 16:01

I was looking at getting a newer used Ford Ranger 4.0L or Mazda B4000
extended cab 2 wheel drive truck. I have read that the gas mileage is
almost the exact same with the 3.0L and the 4.0L so might as well go with
the bigger one - right?

Here is the question. I read that the compression on the 4.0L is 9.7:1 -
This is really high yet they say it can run on regular fuel. What do you
guys find? Are your engines pinging on regular. What is everyone using for
gas in these? Comments......

9.7:1 isn't "high" compression. If the users manual says to burn regular
fuel, that's what you should burn. It's a waste of money to burn higher
octane than you need.

I have a 1997 B4000 with the 4.0L engine; I use regular gas, never have had
any pinging.

9.7:1 isn't high compression.

I have a friend that has the 4.0L Ranger (2001 or 2002 I think) and he says
he burns regular also and finds it okay. Good to know you guys aren't
having a problem. Currently I have a 9.5:1 4 cylinder car and it says to
run on regular but it makes a high pitch pinging sound when under heavy
acceleration. When on a higher grade of gas it goes away 'mostly'. I have
to admit though, I don't agree with the statement that 9.7 isn't a high
compression to run on 'Regular 87 Fuel' though. If it is working though, I
won't complain and put in the cheaper stuff if I buy the vehicle.

Thanks All
