I have a 1966 Ford 289 with about 25,000 miles. Obviously it must have sat for long periods of time. I do know that in the previous ten years before I bought it, it was only driven for short trips. 2-5 miles at a time. I have had it for a short period of time but after buying it I put in Valvoline VR1 Conventional Racing Oil 10w-30 after asking many people with old cars. I use ethanol free gasoline 90 octane. The oil analysis was fine except for the lead. Last year it was 630 and this year 403. The engine does not smoke or make any unusual noises and it does not use oil. The oil pressure gauge works fine and shows a good oil pressure. (No numbers, but right in the middle of the scale.) Why do you think the lead numbers are so high? Possibly the previous owners used leaded fuel or a lead additive in the fuel? I guess it could be the bearings but like I said, the pressure seems fine. Any thoughts would be helpful. Thank you.

The car spent most of its life using leaded fuel. The falling lead number is consistent with residual lead coming out of the engine as you use it.

What ecotourist said. The lead count is not a problem.

That engine will have plenty of lead in it after years of running on leaded gas, don't worry, and the VR1 10W-30 is an excellent choice.

The lead from the gas will stay in it forever.

The lead in the fuel back in the day used to help cool/lubricate the exhaust valves. What serves that function in today's lead-free fuel?

Thanks for the quick input. That is a relief. Now to go drive it!

No Lead: I don't plan to really push the car very hard. No racing, no towing, etc. So I should be ok especially with the limited miles that I will put on the car. Maybe 500 miles per year at most. I am old enough to remember the American "white gas." American sold high octane no-lead in the 1960's at least on the east coast. The older fellows with the Corvettes and GTO's and other muscle cars used to fill up all the time with that gasoline and I don't remember them having problems. Back to today, I checked with a lot of local guys with cars that used to run on leaded fuel; now they all use unleaded with no problems. Of course, like me, the mileage is limited.

Nothing in today's fuel serves that function.

Hardened exhaust seats and better valves did away with the need for lead lubricated exhaust seats.

An older engine without hardened seats will last a long time if it's never driven very hard.

Now, truck engines are a different story. When leaded gas went away in 1992 or so, all of our 1-1/2 ton & larger trucks sunk the exhaust valve seats pretty quickly.

In the late 70's I had a 67. Something rubbed a hole in a power steering hose. The shop replaced the hose and the cry pump.

Back in the early 70's I drove a very nice full size 1966 Custom 500 with the 289 engine. It was actually a very nice car with good power, comfortable, roomy, decent mpg. However, the 4 wheel drum brakes were scary compared to today's disc brakes crzy .

Nothing in the fuel does now. Modern engines use hardened valve seats, like stellite.

That's believable. Back when leaded was going away, there was an article in the SAE magazine on that issue. The quick synopsis is that old engines without hardened seats need to stay under 3000 RPM when running unleaded fuel.
