Title: Oil change to 0W-30 for less clatter
Post by: Michaelflat1 on February 13, 2018, 01:31:16 PM
Inside the car I believe it has 5W-30. Its OK but on a cold morning we have to drive up a rather steep hill (up to around 3K revs at like 20mph). And the clatter is quite bad, sounds like a diesel if not worse! I think an oil change is overdue and I don't know when the oil filter was replaced.
But it is quite an old car, some say that on an older engine it shouldn't have thin oils. It's an 07 and around 80K miles. Hasn't broken down in 10 yrs, excluding batteries.

To add, right after the oil change when we started it it was so quiet, the only way of telling it was on was a slight noise under the bonnet and the rev counter. With the bonnet down you could not hear it!

Engine oils do 'break down' when they have been in too long,  the longer polymer chains get broken up and oxidised and the oil thins out - viscosity improvers are added to oil that swell as the oil heats up to maintain viscosity,  these also get damaged.  The reason synthetic oils are much better is that they maintain their viscosity longer and over a much greater range of temperatures.

My son-in-law (mechanic) discussed it with his oil supplier and was told not to use thin oil in a high mileage engine. Told to use 5W-30. I use 5W-30 in my 100K+ engine. Hot or cold, my engine is quiet as anything 5,000 miles after the oil was last changed. If yours sounds like a diesel, might I suggest you check (or have checked) the valve clearances.

A 5w30 oil, meeting the car manufactures specification is just fine. Key to a smooth, good running engine is changing the oil on time!

We drive many shorter trips and since we have the car, oil is always changed twice a year (4000/5000 km) with a 5w30 synthetic oil. Cold weather or not, the car is always running smooth and quiet without weird noises.

There used to be, maybe still are 'high mileage' oils for vehicles that have done over 100k that are higher viscosity to slow down burning of oil and to keep oil pressure up even though bearing clearances have opened up. May also have seal conditioning additives to make hardened seals more flexible.

That is, without doubt, the best thing you can do for any engine. 12,500 miles seems a long time to me between oil changes, synthetic or not!

Personally, I don't see any reason to use anything other than a good quality 5W-30, should be plenty thin enough.

+ 5w30 seems cheaper than 0w20
