Which is best oil for my needs?

paulh260260 · 30th September 2021, 09:18

Guys

Hopefully I'm not opening a hornets nest here but, as its the winter service time, and my driving has changed this year, I'm seeking advice on the correct engine oil specifically for my own needs,so...

Most of my driving is now very short journeys, either 4M round trip on A roads or the occasional 8 mile motorway trip to pick up SWMBO.

As I intend to flush the engine and change the oil and filter every 6 months is there any reason to change from the recommended 10w/40 Mobil 2000 semi synth I normally use?

BTW its a 2.5 L petrol model with A/C which has done 64K miles.

Cheers

Paul

Go on then....

I'll put in my twopenneth....

Short answer - No.

Longer answer:

Yes. As you're now doing short journey's and it's through the winter I can't see any harm in using a 5W-30. My thinking goes like this:

1) 5W-30 is thinner so will move around the engine more quickly from cold and with such short journey's I'm not sure that everything will warm up completely.

2) We're moving into colder weather so it's a double whammy about the oil and engine getting up to full operating temperature.

Having said that, I run a diesel and don't know how quickly a V6 warms up but have been doing my own oil changes for more than 4 decades (who else remembers Duckhams Q?)

Very happy to hear from those with more technical knowledge

I remember when Duckhams Q20/50 was 16 shillings and 9 pence per gallon from a tyre fitting place in Nottingham.
That's 84p for 4.55 litres for our younger readers.

Hi Paul.
Stick to using the 10W/40 as it is good for between -20c to 30c toping up or changing the oil it must meet the ACEA specs, in your case ACEA A2, oils of higher numerical specs can be used (eg ACEA A3 could be used in place of ACEA A2 for ZT 160 models, but oils of a lower numerical value must never be used.

On a diesel you could use 5W/30 in the winter months as the engines tend to take longer to get up to temp even more so on a short journey as you have listed

Short and long answer is stay with the oil you are using, perfectly excellent, unless you live in Siberia, you can use a thinner oil, but I would not waste money.
Check in the driver's manual to see what was recommended and stick to that.

Thank for all the replies guys, as I've still got some 10W/40 it seems that will be OK

As the others have said. Stick to your regular oil.---By the way, oil doesn't have to get hot to work. Within a second or two from start up it's doing its job.--Condensation, on short runs, is the engines enemy.

In fact most of the engine moving parts are splash fed. Even pressure is not vital. The oils first job is lubrication but just as important is heat removal from the pistons and big end bearings. etc.

Condensation in the engine will effect the oil so more often oil changes are essential to its well being.

Do just what you are doing and all will be OK.---

I have used Castrol Magnatec 5W-40 on both of my Rovers for ages (45 k1.8 Petrol, 75 2.0 v6) and at least on the 45, the oil performed much better during the cold winter months than 10w-30. I didn’t have an engine block heater on the 45, and it sure started every time very happily, when there was charge on the battery. The oil has not given me any issues and I’ve found it to be easily available and not that expensive, I recall it costing around 5€ per litre at my local auto parts store. I can recommend it regarding my own experience, but I could be wrong too.

Ps: Last winter we had very very low temps (-25 or more) and the 10w30 oil wasn‘t gonna cut it for me

Follow The Handbook, you'll not go far wrong. Note that the ACEA parameter is most important.
