Hello,

I have a 1641cc engine (professionally done - heavy duty springs, Engel camshaft, etc..) that also has a full flow engine oil cannister filter. Its about one year old and it runs OK but there is a slight gurgling noise when I go uphill and I am in a higher gear. No biggie, I change down and it goes away...

I'm living in Melbourne and as you know it gets a little cold in Winter - its about 5C in the mornings. And it gets a very hot in the Summer - 40C.

At the moment I'm using Valvoline XLD Premium SAE20W-50 API SJ/CF. I just buy three 1 litre bottles because it makes it easier to estimate the 2.5l and easier pour out. I don't like using funnels... its so much simpler to use the bottle then chuck it away, leaving nothing behind to drip oil or clug up the garage.

I am not particular about the cost - I change the oil every three months or 3000 miles and I don't have any problem paying a little extra for a premium oil - so long as it does its job well. Relatively speaking, it doesn't really matter- the cost in petrol dwarfs the money we spend on engine oil.

What's a good oil to use in the Summer and Winter? Can I keep on using the same Valvoline oil?

And 2nd question - should I add in 100ml of extra oil to compensate for the oil filter?

Cheers!

The transmission? Um... I don't know really. The tranny is a new recon. It only happens when I am in the wrong low gear.
