Gas is a funny subject…especially when its so expensive now. I’ve used cheap and expensive. Here are my findings:

93 octane vs 87 octane

No difference. Runs the same no matter what the level is

Additives

I have noticed a difference in power when using 87 octane and an octane booster….the STP brand in the orange bottle. The truck was more responsive and ran smoother…

I still believe 93 is a waste of money and i think any additive will really give you a performance boost.

Engine temperature vs 87 octane

I have noticed a significant difference when running 87 octane and using a 190 degree (or more) thermostat. I read somewhere that lower octane needs higher temperatures to burn, in case you need some background before you decide to go to the local auto parts store and buy a high temp therm.

The only downside: the engine will be pretty hot…especially in the summer months, so you may want to run a super-coolant additive and/or use a failsafe thermostat.

Unfortunately, only lucas parts will work. If you use anything else, you’re gonna misfire or not pass inspection. There seems to be an issue of craftsmanship that either the US part makers or Lucas screws up.

I bought the Beck/Arnley version from partsamerica and unlike the Lucas, it had a dull, rough finish and fit loosely. The Lucas part was shiny and fit like a glove.

If you plan on splashing around in the water, you may want to just buy the Lucas…Its blue, btw.

Atlantic British has the best deal for them.

As far as wires, rumor has it that the Lucas “leads” are the only wires that will work. That’s a myth. However, you cant just buy any type of wires. I’ve had success with Autolite Pro wires i bought from partsamerica.

Rover connection sells the high dollar Magnacor wires and atlantic british has the “updated” rover wires.

Napa also has a set (1756008 -> $42)

If your rover starts to misfire at mid range speeds, this sensor might be trashed. Its designed to misfire at high speeds to slow your truck down.
