Right guys and girls.

Oil change is imminent and im confused as to what oil to use. With the high millage on my F I was going to use 10W40 but am unsure now, 5W30 or 10W40?. Please help!

V6s are, I believe, quite fussy...

but why 5W30 or 10W40? - there are more grades available

I used 5w30 in our 120k motor and it's running like a dream, ours hasn't been fussy yet with oil.

If you don't burn oil then that is what I would use

5w40 would be good if you were worried about oil consumption. 5w30 if the engine is still a good one.

Why didn't you do this oil change before you put a load of treatments and additives in? A good oil change with a decent oil may have helped your problem anyway

Did you ever hear his engine? I don't think even the best and most expensive oil in the world would have sorted that.

I just thought these were the ideal oils for the V6




I put it in to see if it made any difference, and it has. I was able to pick the treatment up cheaper thanks to a good friend i will be adding another bottle during the oil change.


The engine doesnt burn any oil, just noisy on start up. She still pulls very well, im sure _stuz_ will vouch for this

What are you running now; semi synthetic ? or full synth? Always stick to what you have. The viscosity doesn't makes a lot different.
Mazda recommends 5W30 for the V6

I used it a while, full synht 5W30 Castrol Edge but I am now running on the 0W40 Castrol Edge Sport for some heavy use of the engine

Im not sure whats in the car at the moment.

Think its going to be 5w30 semi then when I do the oil change

Let me know I will sort out some cheap for you.

I will vouch for the car pulling extremely well, yes the treatment is uber cheap too so it was worth a punt.

overall it's a cracking engine for 160k and I would say it has been looked after well previously.

What you think
