ehats the best oil to use in a 1995 Chim with 85K miles on.

A non-mineral based (ie synthetic) oil, such as mobil 1. The only problem with that is that Mobil 1 is 0W40 spec these days IIRC so perhaps a bit thin for a higher mileage car.. I think there is also a Mobil Motorsport Oil at about 15W available otherwise I think Millers Full Synthetic is something like 10W40 from memory (and a bit cheaper than Mobil Too).

Cheers,
Matt.

15W/50 Mobil 1 Motorsport (Halfords)
10W/60 Millers XFS or
Any good mineral oil changed more regularly. 20W/50 is fine.

From previous threads, most folks use a semi-synthetic or fully synthetic oil and most avoid 0w40, since it's thought to be too thin. I run mine on castrol magnatec 10w40 and have the oil changed every 3k.

I'm still a bit confused about what the oil ratings actually mean, from reading previous threads I'd got the impression that the first figure was related to the temperature at which the oil reached its rated viscosity, and the later figure relates to the viscosity, is this right? or could someone explain how it works.

Viscosity is a measure of an oil's thickness, or resistance to flow.

Low numbers indicate thinner oil and high numbers indicate thicker oil.

Multigrade oils such as a 10W-30 are designed to have the viscosity of SAE 10W oil at cold temperatures and the viscosity of SAE 30 oil at engine operating temperatures.

The "W" or "Winter designation indicates that the oil meets viscosity requirements for low temperatures (below 30°F).

In a nutshell.

ps. SAE - Society of Automotive Engineers.

Just did a quick search on Google, because I didnt know either!
