Forgive me if this has been covered I done a search but could only see reference to turbo engines,
I like to keep an eye on my fluid levels on a weekly basis when I clean my car, I noticed over a period of a month or so my oil level was getting lower - I wasn't really fussed as I am due a service soon anyhow but I had to do a long unplanned journey at the weekend so to be on the safe side I topped up with 5w30.
Performance wise nothing has changed but sound wise it sounds different I feel, it's a bit too tappey under load, I've never noticed it before - sounds kind of like a couple of ball bearings in a tin being shook but not as loud as that obviously as then we would have a real problem!! It can only be heard when accelerating I am guessing it's because I am using a thinner grade oil would this sound logical?
Can anyone tell me what I should be using for a 80k engine. Sorry if I had a handbook I would most certainly look in it but I don't have one I am afraid.
