Oil?

[Danny Boy]

I was wandering what your opinions on this are:

 

Whats the best oil type/grade to use on a 2.0ltr petrol 1998 Galaxy is?

 

Does anyone rate Castrols Magnatec range?? :unsure:

[Guest Andy]

i use mobil 1 at work:5w-30(zetec),10w-40 most other types of engine,

my 1995 2.0ltr runs fine on 10w=40

:unsure: :lol: :lol: :lol:

First of all you didn't say the Mileage on your 98 Gal and how much oil it may be using. No point in putting the thinnest most expensive oil in an engine which may then only use more because the oil is thinner. Its a cost/ benefit choice.

FULLY synthetics ( 0W-40's) are the best oils in terms of wear and performance and can be used for extended service intervals provided they retain their lubrication and detergent properties. How do you find out? Send a sample for analysis(?) I suppose (unless you have a temperature controlled Viscometer when you can do it yourself).

I think Mobil 1 is available now as (0w-30/40's) grade and on a previous Volvo, Micra and Rover(in its early days). I always used Mobil1 (5W-40's) but it is expensive. I always tried to buy enough when on hols in France.

Be aware that the detergent properties of fully synthetcs are much superior to non synths and will "reportedly" shift residues ordinary oils will not reach. (Article I read by HonestJohn the telegraphs Motorscribe) he suggested that if you did change to Fully synthetics you must go to much shortened oil service intervals (1000miles) until the oil is no longer Black (How black I don't know but diesels always seem to be that colour).

Far too cautious for me and very expensive. I would Flush with a standard non synthetic having run it for a few hundred miles and then change to the synthetic. If I started to worry halfway through to normal service interval then I would change the oil for synthetic again but without flushing this time.

Of course this is not necessary with a fairly new engine (upto 20,000mls ?)

But this depends upon the conditions of motoring ie Lots of stop start cold working conditions= Old engine . Lots of Motorway cruising= New engine.

Semi synthetics seem to use a synthetic "Base" (whatever that means?) but also have superior detergent properties and as such are not to be dismissed. Only the comparative price does this for me.

Well my petrol has done 120,000 miles got a tappet problem and obviously want the engine to run as long as possible, it doesn't seem to loose oil so thats not a problem, but my journeys tend to be no longer than 10 miles and sometimes does involve a lot of stop starting. The oil in there at the moment is looking thin and dirty so i was going to do an oil change but was undecided as to what oil to put in?

 

I do a long motorway run about once a quarter and its mainly driving round town that i do but still manage to clock 300 miles a week!!

Does your Galaxy have Hydraulic Tappets

I used to, and many other people also had a problem with the exhaust "Self" adjusting Hydraulic tappets on the Honda 2.7 V6 used by Rover in their 800 Stirling Model. I knew because you could hear them at low revs. As revs increased the hydraulic valve would eventually lock up and the noise would go away. You had to adjust the Valve clearances just a bit on the close side.

 

Before I realised this I solved the problem by using Castrol RS 10W-60's oil which meant the oil stayed that little bit thicker and didn't leak away so quickly from the Hydraulic unit so fast. Previously I had used Mobil 1 0W-40's

So a slightly thicker oil at the high temp side may help.

I certainly would not use a 15W-50's unless I was burning lots of oil 1L/1000miles?
