My 1968 Ford 302 has covered 6,000 miles since October. I use non-synthetic SAE 20/50 oil. What service intervals should I use?
I will be changing the oil before I go to Silverstone but wondered if there was a specific service interval for mineral oils. (If I remember back to the 60s/70s I used to change my oil twice a year)

Thanks David, that's what I seem to remember too. I just wondered if there was any increase in frequency nowadays or not. My BMW Diesel 330 only gets an oil change every 20,000 miles!
Still better safe than sorry, good job for next week then!

Clive,
I have a 330dTouring and I agree the service intervals do not seem normal to us older folk.
I think it is a great car but it is going in next week for a new wheel bearing (29,000 miles) and when it was new i had problems with the on board computer which baffled the dealer for a while. It is also amazing that it has an average fuel consumption of 40mpg.
cheers

Why? I use Silkolene 5W/50 fully synthetic - the car sits for long periods without running, and synthetic gives much better long-chain protection for cold starts. Many US owners use synthetics, too - you need to be careful which minerals you use, as their constituents change with the times and there have been several instances in the States of mineral oils allowing the lobes to be wiped off flat-tappet cams.Migge wrote:Always mineral and 20/50.

Hi Roger,
The reason why you should use non-synthetic oil in older engines is because the synthetic oils primarily contain less additives, especially zinc, and this is harmful to the inner engine seals and consequently reduce the life of the engine.
I spoke to Peter Knight of Knight Racing Services (My engine supplier) http://www.knightracingservices.co.uk this morning and he told me to never use synthetic oil and preferably use Valvoline 20-50 (But not 20-50 racing oil) He also recommended using Blue anti-freeze.

Not been able to get Valvoline so phoned Peter Knight who recommended Millers Oils http://www.millersoils.net/1_Millers_frame_CLASSIC.htm
