do you mean 20/ 50w  oil  as 15-20w  is a thin oil. i wouldn't use it in my sewing machine.  I have be using Castrol Edge Sport 30-50W . It is made for big bore motors and suits well, especially in hot conditions or in traffic the oil pressure stays high.

Go the Castrol Edge Sport 25W-50, or Penrite HPR40, as both have the required zddp (phosporous/zinc) content to protect our flat tappet engines.

Friends race historic cars on these two oils with no measurable wear after a season.

Strange but Penrite HPR30 is less suitable, being an oil with less zddp content for modern engines.

Running the oil warmer (85C min) rather than cooler gives the best wear protection.

This is the correct answer, but HPR 30 is still ok, once the cam is bedded. Just remember the heavier the oil the more HP it uses to pump it around + the slower it is to get around on start up, and if you run a HV pump the harder it is on the drive gear on the cam.

Penrite Classic is there best blend for flat tappet and early engines which need Zinc etc. Any oil that says it is suitable for 'late' model cars is a worry, due in the main to them having to remove all Zinc and the majority of Phosphates to make the Catallytic converters live.

In Penrite Classic you can get light med and heavy, google their website and study for yourself.

Hi all, I know this is an old post and some of these products are hard to find now.  Just looking for an update on what oil would be best for a 351c runs fine and not rebuild recently in Queensland.

Thanks
Cheers Glen

Glenn , 351c Penrite  HPR 30 , 5 litre  with a Z9 oil filter . Put some oil into the filter 1st with some oil around the seal .  Put 4.5 litres in and check level ,but with the new filter  ,  after its run and the cooled back down and checked . Make sure the old seal comes off the block .

Glen, my 69 with XC 2V takes a little over 4L with filter. I would do as Glen70 said start with 4L and check, lot easer to add more than take it out :grin:

Thanks guys,

Great advise and spot on as usual.  I was leaning this way but always good to have some experienced advice.

Cheers

Hey Glen,
Before you buy your oil check you have a standard size engine oil pan!
If not and the oil level is right on the dip stick empty the oil into measuring container.
Then you'll know what size container to buy!
Add a little bit more for your filter!
Cheers Phil.

Hi all,

The change went well.  I did a flush and let it drain out completely.  I put in ~5.8 litres which was surprising and when I have checked a few times it is in the middle of the "safe" zone on the dipstick.

Is this all ok any concerns?

Thanks

Glen
Cheers Glen
