Hey Guest one of our sponsors Progressive Parts is running Black Friday and Cyber Monday offers - more details here
Looks like you got some great results there. It would be very interesting to see a comparison with one of the "lesser" brand 5W-40 fully synths though. I may have mine analysed when the time comes. What are the costs involved?
I usually change every 6000 miles maximum. At the moment I'm using Unipart Branded 5w-40 fully synth which is exactly the same oil as Fuchs SuperSyn: http://www.opieoils.co.uk/p-984-fuc...h-performance-fully-synthetic-engine-oil.aspx The only difference being that it costs me less than £20 and I get 5 litres instead of 4.

JFYI the sxoc did an independant test of their members oils a little while ago, IIRC most of the fully synth came out as at roughly the same, apart from castrol which came out as changing its viscosity!
You have to be cautious when changing oil too frequently as new oil eats away at the seals in your engine, sticking to the manufacturers recommendation is probably best in this rare occurence!
Never heard of this before and I've done hydraulics for 12 years.
If the engine is ment to take oil (which obviously it is) it will have oil resistant seals in it.
The cost is £30 for the all singing all dancing tests.
I would strongly recommend this service and Millers oils. As said this allows me to work out how often 'I' need to change my oil, other may need to change at different intervals but until you've had this done you'll never really know TBH.

I wouldn't use a lesser brand, I won't compromise on oils, petrol or tyres. The best is whats used, simple as.
Many would say (I wouldn't) that Millers is a lesser brand. I've always used Millers XFE-PD in my diesels, I think its great stuff but I don't think any of millers oils are necessarily better than the likes of Comma, Valvoline, Fuchs etc just because they have a Millers sticker on the bottle. There is very little difference if any, in their composition. Fuchs and Comma especially have an outstanding reputation, better than Millers outside of VAG circles. We use Fuchs oil in the guise of NATO designation OMD90 in our Warrior AFV engines which are upwards of £100k each, its not used because its cr*p oil.
A fully synthetic 5W-40 is what I've always used in my petrol cars and its what I'll continue to use. Just as it never gets anything less than either V-Power or Tesco 99 and Goodyear Eagle F1, Bridgestone RE050A or Toyo T1R tyres.
If we were all brand conscious instead of content conscious, we'd all be buying Mobil 1.
Indeed they do mate. I've just read through your progress thread, you've done some great work there, definitely something to be proud of.
Just noticed this:
Thats a crazy statement mate. As JS said, your seals are oil resistant. What they are not resistant to is the corrosive combustion by-products and acids that become suspended in your engine oil over time. Short journeys = change oil often.
Chill out people, I am not an oil anorak so am just passing on info I have recieved second hand, here is a quote from someone who works at Ford, it looks like it applies to sealant and not seals!
"Chatting to someone at work today about this and it looks like its from the silicon sealer used on the oil pans etc as oils are not checked against their errosion properties to RTV silicon sealer, everytime you change your oil its just taking a little out of the sealer The levels I stated are completely normal and are nothing to be concerned about "

Silicon sealant is not used on oil pans. Its either a solid state gasket or an anaerobic sealant, one that hardens when it loses contact with air (ie, between two metal bodies). Neither are affected by oil.
Silicone sealant isnt used in place of a seal/gasket but very often it is used to compliment a seal, usually where there is a join in a face or a sharp angle
Well like I say I know FA about oil/seals, but the person I am quoting works in Ford's development department.
I know they used silicone bonding sealants a number of years ago but I haven't seen it used on pressure or oil bearing engine mating surfaces on anything I've worked on in the last 10 years. Its certainly not used on VAG oil pans unless the oil pan has been removed and re-fitted by somebody resembling a John Wayne character.
Its not used as a replacement to a seal but at a point where a leak could occur.
For instance on a sump that covers a block and timing cover, at the point where the timing cover meets the block the mating face for the sump isnt perfect, applying silicone ensures a good seal with the rubber gasket, likewise at the other end with the rocker cover gasket, also on rocker covers where there are 2 semi circular cut outs in the head and the rubber gasket fills them gaps, the edges where it starts to dip are a good place for silicone to prevent leaks.
I've seen it done on Saab rocker cover gaskets with a semi circular cut-out. I'd be extremely reluctant to use it anywhere it could come into contact with sump oil though.
Dont get me wrong here we arent talking squeezing large quantities of silicone into the sump or anywhere else for that matter lol, more a smear over with the finger. Nowadays it does tend to be instant gasket which is still similar but a bit more specific for the purpose, and i believe actually from just looking it up it is resistant to oil and coolant etc.
vauxhall use it a lot as a replacement for the sump gasket altogether, but they reccomend the use of a specific type
don't ask me the tech spec (got it at work) but its well expensive

Sorry to dissapoint you all but The whole VAG range use silicon sealant to seal their sumps (I've changed mine) but this will be oil resistant (unlike in the Fords,lol).
My sump was on for 80,000 miles with no sign of any leakage.
ANYWAY!!!!!!!
Millers oils........BRILLIANT!!!!!!!
