Hi,
Can anyone recommend the best oil type and brand for my CF 340 Glendale on a 1978 plate please? Thanks :)

For engine oil type see Engine Oils in Help centre ‹ Public Library ‹ Service Data. :thumb:

Which brand to use usually is a matter of personal choice and cost. :)

Hi Phil, what do you think of Halfords Classic Oil 20W50 ? can you recommend it? I was also thinking of purchasing Lucas Oil Leak Stopper. The review seem pretty good but would like to know your thoughts on this too please.
Thanks

No idea about Halfrauds apart from cost being somewhat over the top on some stuff.

Leak stopper additives usually don't help with the graphited rope crankshaft rear main seal on the Vauxhall OHC petrol engine (or Perkins 4.108, 4.154 with similar rear seal design), or with any rotating shaft seal where the shaft is sloppy in its bearings.

Halfrauds haha! I found a shop that has a good selection of oil and they recommend the 20/50 so I'll use that when I do the oil change. I did buy some oil leak stopper so will give it a go and hope for the best!
Thanks for your advice :)

20W/50 should be fine during present warmer weather but might be too much for the starter motor in winter conditions when 15W/40 will be better.

One thing I have noted amongst realistically priced brands of oil these days is that 10W40 Mineral oil is becoming rather more u :idea: uncommon, with the only mineral oil stocked being 20W50, and the only 10W40 oil stocked being semi-synth.

Assuming the preference is for 10W40 mineral oil, which is the 2nd-best choice? The semi-synth or the 20W50?

Ta!

Semi-synthetic oils tend to have later spec. detergent properties which can lead to problems especially if tar and gum deposits are doing more to seal oil passages than tired seals, e.g. oil pick up pipe to crankcase seal.

Why 10W/40 in particular? 15W/40 should be fine down to -15C, i.e. throughout the year in GB.

Hereabouts MOD (Motor Oils Direct) Eurovis SL spec. 15W/40 is readily available from the local spares shop for about £12 for 4.5 litre, a bit less when bought by the case (4x4.5litre).
