Been searching for Millers Pistoneeze but found this.

https://www.classic-oils.net/Classic-Oi ... tage-20W50

It is considerably cheaper but has a similar VI and a greater amount of Zinc.

Has anybody used this?

A local chappie is involved with a "general classics" car club, and he runs the "shop". They sell that stuff, reckon it is OK for most people. Doesn't the TSSC shop sell it too? Not a bad recommendation (I hope!)

Wouldn't be my first choice for a car that is driven hard though.

I must confess that I don't buy oils with unknown (to me) branding. I'm using Castrol Classic 20-50 in my Dolly. Yes it's more expensive, but I feel, rightly or wrongly, that it will be better for the engine.

I use Morris golden film 20w50, and have had no problems :D But i do change mine every year regardless of mileage...... Sometimes clocking up as little as 600miles as i have three classics. Maybe this is being wastefull, but still a hell of lot cheaper than an engine rebuild.
It would be interesting see how often others change their oil?

I have also heard very good reports on the above oil as well, as it supposed to be the same as Halfords, but dont quote me on that. It certainly holds good pressure on tickover on my mates Dolly.

Rob Marshall has been doing a lot of investigation and research on oils lately and he recommended to me an oil i'd never heard of, called Mannol Safari which is a 20/50 with an API rating of SL/CF - quite high! It's also pretty cheap, I was able to go onto ebay and buy 4x5ltr cans for under £40 delivered (this particlar special offer has now ended but the same supplier is now doing the 4 cans for £42odd, still a good deal!) Rob is using the stuff in his OHV cars and I have used it in my fresh rebuild of Andy P's 1500SE motor.

I probably wouldn't use it for a competition app, but it seems fine for everyday use and makes sense for cars that do low mileages but still get their oil changed annually.

Rob also recommends the Mann W713/14 oil filter, which has not one, but TWO anti drain back valves, for use on OHV engines. I can attest that this REALLY works, From a cold start after standing 2 days and without priming of any sort the oil light was out within 1 second of firing and maybe 3 seconds of total cranking, with NO start up grumble whatsoever.

I second the above. On Monday I fired the engine up after three weeks of inactivity and the oil light went out straight away.

I use this one on my big six's also with two drain valves, it might be a bit long for ohv Dollies though?

I will also check out the above oil :D

Most classics are not driven especially hard nor does the oil tend to stay in there for an extended period. A good quality oil with a decent level of ZDDP is all that's really required. Unfortunately most manufacturers do not disclose the level, some don't even disclose the API rating.

That won't fit a OHV dolomite. The OHV use a 5/8 threaded filter, which is difficult. Caledo's one I havenever seen before, and is a good choice.
The one here is a 3/4 thread, common to about half the cars ever made. Ford, VW etc etc etc And is used when a spin-on conversion is used.

Saying all that, I imported from the states 20 adaptors so 3/4 threaded filters CAN be used on the OHV engines. I have your filter on my mk3 spitfire....

And yes, almost any oil is OK for most drivers. Different matter if used for trackdays/long fast journeys(RBRR, 10CR) and so on.

Post subject:  Re: Which Oil
I second what Steve and Mark have said. The general consensus is that it is best to use a decent brand no matter how the car is used. Millers is my brand of choice because I can source it for a reasonable price from a local motor factor I've used for many years.
