I’m sure the oil question has been asked many times here but can I ask what is the most suitable engine oil for a 19 year old Peugeot Boxer Engine? Thanks

What ever is specified by the vehicle manufacturer.

If you’ve got the service book it will tell you in there 👍

I found the recommended oil in the Peugeot handbook! But being a bit of a novice on diesel engines the best oil is still a slight mystery. It says:
Diesel Engines
Esso Ultron Diesel
Total Quartz 9000
Total Quartz Diesel 9000

The vehicle is 19 years old, therefore I assume oils have maybe moved on since the book was printed. Does anybody have advice on a modern equivelant oil to these?

Thanks

I’ve used this in my 2001 2.8idtd based hymer

If the engine is that old, just leave it to the discretion of your servicer (if you trust him). Otherwise most modern oils should do no harm.

I was just needing some for topping up occasionally, as you say the servicer ( who I trust) would do the complete oil changes.

Whatever they put in 19 years ago has kept the old girl running fine, why change a winning team?
Yes indeed! She’s actually only done 28000 miles in that time, I was just thinking of a modern equivelant to what itvsays in the handbook.

It was this Coma oil I used .. from 'Motor Parts Direct', they have store local to me

Thanks, the Comma Oils seem a bit more reasonable than the “big” names.

We use Castrol Magnatec because our van can stand for a few weeks without being started. It’s supposed to be good for that. I guess it must be working because our Euramobil is nearly 30 years old and going strong.

That sounds a good piece of advice.

An A3 B3 10W/30. Stay away from cheaper brands. My husband is a professional automotive engineer.

Stay away from cheaper brand

Good quality oil does not have to be expensive but it does have to meet the given industry standards and the standards the engine manufacturer advises.

I use Comma , it's not a 'cheap brand' but it is cheaper than many of the 'big name ' brands. It meets or exceeds the standards for my engine.

Comma is a world-class manufacturer and supplier of automotive lubricants and chemicals for passenger and commercial vehicles.

If not convinced try searching Comma

Most important is the specification. Always use the grade and API specification as written in the handbook.

Engine and Oil technology does develop over time, and the specification evolves and improves. There is no danger at all in using a later/more modern API spec in your engine, as long as the grade as stipulated by the engine OEM is used.

The oil grade will be something like this, 10W40 or 5W30 or even the old 20W50 ‘multi grade’ - the old term used to describe the blended and more engineered and often semi synthetic oils first introduced to provide far greater protection over a range of temperature.

The first bit refers to the required W or winter viscosity. The second bit refers to the oils viscosity when hot. A 10W40 multi grade oil will exhibit the characteristic resistance to flow (viscous) behaviour of a very thin base oil (one with a dynamic viscosity of 10 centistokes) when it is cold, and it will exhibit the characteristic resistance to flow behaviour of a heavier base oil (one with a basal dynamic viscosity of 40 centistokes) at high or operating temperature.

All mineral oils will quickly degrade over time. This is traditionally mitigated by adding stabilisers, preservatives and conditioners and other additives to prolong life. These oils are called part or more commonly semi synthetic.

The very best oils are fully synthetic. The best oil you can put in your engine is any modern fully synthetic oil of the correct grade (as stated by your vehicle manufacturer) that meets the latest API spec which I think is currently API-CJ or CK4

Why? it will work harder, resist thermal and chemical breakdown better, produce less deposits and stay in grade longer.

Unrelated to MH, but maybe relevant.
I run classic car (1950 Riley RMC), it spent several years 'resting'. When I reactivated it in 2018 I looked for an inexpensive oil, believing that 'things had progressed in the last 25 years'. I chose Comma Vintage and Thoroughbred, and at first start up, all was well, however after a few hundred miles oil pressure dropped off and would not rise to a satisfactory level. In desperation, I changed the oil, to Morris Golden Film, 30 SAE, and have never looked back. I have recently spent over £6K on an engine rebuild, and am reluctant to risk this by using a lesser oil. My engine rebuilder however uses only Castrol.
s well

That’s really helpful I learnt a lot from your post👍
