I have had my 3.4 C2 for about 16 months now. I had it serviced just after I bought the car at 53,500 miles. Mileage is now just over 55k.
The previous owner changed yearly regardless of miles. Currently running 5/40.
Should I stick with 5/40 or change to 10/50 or not waste my money and leave as is until I've done a few more miles?
Dont know

Sadly keep it yearly as many won't touch it without regular frequent changes when you come to sell.

2k miles is a monumental waste of al that synthetic oil though Sad

Please promise to do 10k next year.

There is absolutely no chance of me doing 10k next year. nooo
1500 is about the norm for me.

It's frustrating dumping out "as new" quality oil but as said, it simply has to be done, for the next owner. Mad isn't it.

I'm in a similar boat although I generally do 3-5k per annum.
I use millers 10/50 at £100 a pop plus oil filter (from OPC).

What comes out of mine this year is going in my old volvo. Grin

I agree, it is a bit mad and a total waste. I shall order some Millers 10/50.
Where is the best place to purchase?

Why the Millers 10w50?

I use Opie oils. They often have offers on, but by the looks of it at the moment all there is is free delivery on orders over £60.

This is the Millers a lot of the lads use now. As recommended by Hartech.
You'll need two 5l bottles.

There are loads of other options on the Opie site though ranging from about £60 for 9 litres. Just type your reg in. Thumb

Because it's the best. Why scrimp on the most important thing for your engine?

Unless you mean why the 50 grade rather than 40. That's what Hartech recommend on older or high mileage engines.

My engine has only done 67k but I prefer the extra hot temp protection the 50 offers. Plus the extra .25 -.3 bar oil pressure when hot is reassuring.

Thanks.
Do you always go to your OPC for the filter?
I'm assuming that they would be made be MAN or the like?

I do but you are correct, they are Mann. Even the printing on them is identical.
My Indy gives customers the choice. I just go to my OPC as I'm usually getting other parts anyway.

My indy showed me a few horror stories years ago. One car was in for a rebuild because the aftermarket oil filter had collapsed and starved the engine of oil.
I think that must be etched into my memory, hence the OPC filter. Very Happy

I wouldn't class 55k as a higher miler and I also wouldn't worry too much about the 50 on a engine that doesn't suffer bore scoring.

10w50 everday of the week on an M96/97 3.6 or above, regardless of mileage.

Anyway, lets not go down that topic of how to bring your kids up Grin

I also change the oil every year regardless of mileage. It's not so much for re-sale value concern, as for the fact that water condenses onto cold surfaces inside the engine at night and then enters the oil. Although it evaporates as the oil warms up, I still worry about the damage the water does and for this reason I refresh the oil early in the spring each year.

I only drive about 3000 miles a year, but most of that is relatively short journeys, so I'm also concerned about how those short journeys could do damage with oil that is even a little bit past its best.

Please note that the above is just my opinion and is not intended to contradict anything anyone else has said.

I get my oil analysed each year (135k and want to keep an eye on copper content - the first sign of worn main bearings).

After 6k and 13 months I sent my used millers off for analysis.

They said its fine and to leave it in for another 10k miles.

It was already recycled at the council tip Sad


Good call on sticking it in the Volvo Marky. My 996 is my daily snotter so I don't have that option.

When I was young and stupid (yes it is possible I was more stupid than I am now) I used to use the old oil out my Dad's 405 when doing an oil change on my Cavalier Grin
