Obvious oil question

[maverick dave]

I know the oil topic has been done to death, and I have tried to look through all the old posts but am still confused

Can someone tell me if say Castrol 10/60 is better for hot conditions than 0/40. i think it is.

Also can i mix 10/60 with 0/40? and (finally)

Is it easy to drain the oil and fill up again (I promise to buy the bible soon!!)

Need to know these things, cos i now have my Chim in Oz and its over 30 degrees every day at the moment and the car is running very hot!!! I know its not what you want to hear over there in the UK.....sorry

If i remember correctly, i'd say your 10w60 is by far the better choice, as 0w40 is just TOO thin. Add that with the temperatures you get there and i don't think you should be using anything below a 10W---

All in my opinion, no doubt someone who knows what they're talking about will come along soon.. then another, then another. Apparently PHers are like busses....

Large, smelly and usually empty?

Belching noxious fumes?

0/40 can be too thin..but better in winter (it'll get round the engine quicker).
10/60 is thicker and is better for hotter conditions.

Yes you can mix the oils.

Not sure about last point.

The way I had it explained was :

e.g. 10/60

The 10 is the cranking viscosity - so zero is very thin
and is good so winter starting (10 is also very low).

The 60 is the ultimate protection value (or something like that) - in my book the 10/60 is better that the 0/40.

Mobile 1 also do another grade - 10/40 .. if I remender right.

Quite a few people have recommended a semi synthetic by valvolene (American) it's something like 15/50 and should quite suite the RV8 engine.
