what oil?

[itavaltalainen]

Very much agree to regular changes (you should have seen the oil in the poor Endura 1.3 in my gf's Ford KA  )
Trying to say also that visco does not necessarily have to do with quality (you can find some £hit 5w40s and some good 10w40s with latest MB specs).

.. i run 5w30 A1 castrol magnatec in my little fiesta 1.3 and it's worked wonderfully  but got that recommendation from the castrol website.

i've put my golf's reg in the castrol site and this is what it tells me:

Recommended: EDGE 5W-30       

VOLKSWAGEN

Golf 2.0 GTi 16V

P-Reg

1993 - 1997
 
Recommended for Engine (P):    EDGE 5W-30    4.0 or
                                                Magnatec 10W-40 A3/B4

   Manual Transmission    Universal 75W-90    (a)

   Automatic Transmission    -    

   Differential    From Gearbox    

   Coolant    Refer to Technical    6.5

   Brake Fluid    React Performance DOT 4    

   Power Steering (where fitted)    Refer to main dealer    

   Wheel Bearings    Multipurpose Grease    

 
   
a.    Capacity unquoted

1.    Service Interval QG1 = Flexible Service Interval (Long-life service). Service Interval QG0/2 = Time/distance dependent interval (non-flexible)

Engine - Miles Max    10000
Engine - Km Max    15000
Engine - Months Max    12




So, Edge 5w30 because that's their expensive fancy brand and they want you to shut up and give them your money, and 10w40 A3/B4 because that's the less expensive stuff that will also suit your car

That oil I'd NOT put in any car (same with VW LL2)... very low hths that Ford promotes for fuel economy but it does not save enough fuel to pay for the increased wear in the engine...

[xAntiVenxm]

Hmm.. fair point mate. I've not paid attention to hths much before.. suppose i should really  :embarassed:

might swap for something else next time i service the fezzy..

very helpful this forum! learned something new every time i visited lol

EDIT: While we're talking about it, anyone know where to find a list of the HTHS ratings of oils?

This is a good start for anyone interested in oil specs.
http://wiki.seloc.org/a/Oil_Labelling_Explained
High Temperature High Shear is discussed towards the bottom of the page.

I was thinking that my engine never sees oil at 150°C. But - while the temperature gauge might read 90° I have no idea what it is in the cylinder bores and on the cam lobes where it really matters.

Note that Silkolene Pro S has been rebranded.

On my now sold 1.8t i would.use the very best oil around and something thin to get straight up to the turbo but with my golf i would just put 10w40 in. id steer clear of halfords own but any castrol/mobile 1 part synthetic will be fine and as engines get older id.keep to a thick oil as tolerances reduce as parts wear

thanks for comments guys... till present i have given it a change of oil once a year, after around 8000 miles a year, and have been using VW spec LL2 (as it was free..).. was think of using 10W 40 as a few of you have mentioned.. so may try either the Castrol GTX or Millers stuff..

i'm assuming different brands of the same grade oil will have different HTHS ratings? don't see many HTHS ratings published, will read that wikipedia page and see if it doesn't explain how to determine it from other stats of oil

[itavaltalainen]

HTHS cannot be determined from other oil specs as such, it has to be measured with a viscometer or rather a rheometer... So if unsure just buy one (they are >30k though). 

Joking aside, hths is usually in spec sheet (maybe labelled as visco at 150), along with visco at 40 and 100 °C, TBN, pour point, etc
Google usually does a good job locating those, otherwise email the manufacturer or distributor.

If uncertain what to buy, make sure it's ACEA A3/B3 or A3/B4 and then look for VW 502.00 (petrol), if it has that it's usually already useable, better still if it actually has MB 229.5, that's currently the most strict norm when it comes to cars (except 229.51 which only matters if you have a particulate filter). If you are running a Diesel the equvialent would be 505.00 (but LOADS fulfill this old standard, so not really an indicator), or 505.01 if it's a Pumpe-Düse = usually refered to as PD TDI.

Oils with VW502.00 usually are 5w40, 5w30, 0w40, a very few 0w30 (but then these aren't usually LL2) and even a few good 10w40s.
