Im just intereted to see what everyone else uses.

When i got the car the first thing i did was change the oil and filter. I didnt know about this forums and therfore couldt ask for advice about what oil to use.

The book in halfords said 15W-40 semi synthetic. So i used this. Its good however on cold morning starts it tapps like hell for s few minutes.

I see people here using stuff like 5W-40, would i benefit more from using a good quality 5W-40 oil?

Cheers!

Shell Helix 5W40

Silkoline Pro R(i think) 5W40 (or 5W50 can't remember)

Silkolene Pro R 5W-40

about to put in Fuchs Titan Supersyn 5W-40

5W-40 means the oil is less viscous right?

Would this make the engine more quiet when cold? And would this oil need changing in summer? When temperatures get quite hot?

Either Shell petrol stations for the Helix or oilman, running helix atm as its less hassle to pick siome up when i fill up

the Shell stuff is a bit overpriced though for what it is

True, its dearer than the Silkoline

Have used semi synthetics like Duckhams QXR, Halfords own and Total Quartz 7000.

Castrol RS was best synthetic I used until I used Silkolene Pro S in 5w 40. Mobil 1 in 15w 50 worst I have used.

You don't need much higher than 40w apparently so its more important to get a 5w for low temp protection.

10 -40 mobil 1 also 0-40 mobil 1, like both of those, tried magnatec, that's awful, took it out after a week !

Yeah Mobil 1 is a bag of wank, and magnatex makes these cars sound like tractors

Tis weird Magnatec sounds like crap on my Willy, but on my Valver, made the engine sound sweet as a nut?

Do we get discount at all? (Or do i have to subscribe to this site)

Cant afford £45 for a tub of Silkolene right this minute :P

comma lite 10W40 only opil IO knwo to keep the tappets happy, oil temp down and the pressure healthy. less than £10 a gallon at trade helps to.

15w40 magnatec is what i use. Although its a tad noisy when cold, i just tend to take it easy till warm and then thrash the pants off it lol. Id rather the oil do a better job when its hot as thats when i thrash it lots.

But a 15W40 gives you no more protection at 100Deg than a 10W40.

It's just more viscous at a lower temp, which is worse.

Just what iw as gonna say, not good using a 15w** in mid winter lol

oilman

A lot less engine wear when cold with 5w.

15w is too viscous when cold.

If thats the case why dont we all use 0W-40?

oilman
24-01-2006, 18:48
You could do but -35degC is not really realistic in the UK, 5w is about as low as you need here.

Cheers

I know what your saying but all the manuals i have quote 15w40 for the engine. It might be to viscous at low temps but im sure 5w40 is like piss when at higher temps. I know more engine ware is caused at lower temps but not if you let it idle for a while like i do.

Afterall these are hot running engines

oilman
24-01-2006, 18:56
That is where you are completely wrong.

0w-40, 5w-40, 10w-40 and 15w-40 are all the same thickness at 100degC which is in fact 14cst. That is why they are all SAE 40's.

Fair enough, cheers for the advice and discount oilman!

Shame you dont accept VISA electron on your website :(

8) Fair enough. But what is the need for any other oil then other than 0w-40 and 5w-40 for when its colder?

oilman
24-01-2006, 19:22
It's down to engine wear, the higher the "w" number the more viscous the oil and therefore the harder it is to pump/circulate causing more engine wear at cold crank.

Cheers

You have lost me lol. You said "0w-40, 5w-40, 10w-40 and 15w-40 are all the same thickness at 100degC" So to me that makes 0w-40 and 5w-40 the best as they are thinner when cold and get round the engine easier, yeah? So if they are all the same viscousity/ thickness at 100 degrees whats the point of 10w-40 and 15w-40 and so on. Surely they are pointless due to the other oils being better from cold but doin the same job when hot?

Im not bein arsy, i just dont get it lol :?

oilman
24-01-2006, 19:46
Your understanding is correct. Thinner oils are better always.

10w-40 and 15w-40 cost less in the main, budget grades.

5W40 shell helix is easily twice the price of 10W40 shell helix

I was told by a reanult mechanic (an old skooler) that there is no point using 5w40 in a 90K+ engine. The engines get worn and loose pressure if you use 5w40.

He said use a 10w40 or higher.

I think he's wrong....but there must be an argument for using 10w40, 15w40 etc!

We use 20w40 in our old single cylinder petrol engines as they are worn as fook and just burn the stuff! (Its also the cheapest stuff we can find!!!!)

Next change im doing is for some fully synth 5w40. My semi synth 10w40 that i put in makes the engine tapp like fook, even when warm! Never used to!

Laine_16v
24-01-2006, 20:49
Meh, my engines on 95k and sounds sweet as a bell once warm. Plenty of oil pressure aswell.

Cant see 5W-40 hurting it in anyway.

matty
24-01-2006, 21:11
Way I see it if your engine is in good condition regardless of age and milage, an oil which causes less wear at cold start up is going to keep it that way for longer. Hence why I have used 0w40 in Casrol RS and now the Silkolene Pros S 5w40.

No nasty tapprty sounds like I used to get with higher grade oils and Semi Synthetics.

Silkolene is actually god value as when I got mine it was £33.00 for 5 litres (less if you bought 20 litres like I did) and free postage (from oilman).

Compare with Mobil, Castrol and others who sell you 4 litres a time.

And still an oil change is probably less that what you use in petrol a week yet has to last for 6k. Silkolene is apparently better for a longer drain period too I believe.

False economy if you skimp on oil.

BRUN
24-01-2006, 22:22
the reason a lot of mechanics say not to use fully synthetics is they dont know what they are talking about when it comes to oil
