Have used Penrite oil in my Ducati Darmah for many years without any problems.

I use it in my classic car, best oil in its price bracket IMO

That really narrows it down.
What sort of classic car! Engine! etc

My mechanic swears by Penrite for classics - especially if raced.
Strange that years ago, Duckhams Q20-50, now considered a cheaper oil, was used by many competitors!I never had problems with it and a very hard used Mini Cooper engine that was stripped after 100,000 miles, was only under tolerance for not requiring a crank grind, by a couple of thou on one journal.Mind you, I also added STP to the oil.
On older cars, I believe it is important to never ever run the engine for a short time when cold and make sure the oil always gets up to temperature, even if it means blanking off the bottom third of the radiator in winter.

I use nothing but in everything except my motorcycle and have never had an oil related problem with it or the engines that I have used it in.

On an older engine just make sure you use an oil with a high zinc content because modern oils have a low content due to it damaging catalytic convertors or add a zinc additive to protect the camshaft lobes.

The Penrite range (especially the Classic portion) is a high zddp content oil.
