Title: Castrol Edge 5W/40 Fully Synthetic Oil
Post by: AnilS on September 28, 2012, 02:04:36 pm
As the same here;

http://www.amazon.co.uk/Castrol-Edge-5W ... B004AF34B8

For £6.99 in Home Bargains!

Was out having the Mercedes being attended to when I wondered into the Cape Hill branch (Birmingham). Cheap and handy for top ups.  :happy2:

Shocking, considering I had to buy an emergency 1 litre bottle the other day from a garage and it cost me £18.99  :fighting:

as you ask so nicely  :smiley:

I'm pretty sure the recommended grade for the petrol cars is 5w30

I've been running 5w 40 on recommendation

my understanding is that a 40 grade oil will be thicker at 100 degrees than a 30, is this a good or bad thing? I don't know :laugh:

Yeah thats right. In theory its better for engines which run quite hot, ie the TFSI.  :happy2:

(sorry for my blunt post... wasnt mean to come across like that  :drinking: )

I was under the impression the TFSI needed a thinner oil, maybe using a thicker oil when hot reduces the oil consumption, they can like a drink  :laugh:

Yes, I think its a wise move to use the best oil you can.  :happy2:

Its funny, some do some don't. My first GTI would use a fair bit, but the ED30 and S3 which both I got new did/have never used any oil. Could be down to the running in procedure???? or lack of it

I saw somebody on here nicely explain it the other day. They said something along the lines of, if you drive like Miss Daisy you'll hardly use any oil, but if you drive like a hooligan it will absolutely slurp it down!

I have just recently got Silkolene PRO S 5W-40 ester synthetic oil for high performance engines. never tryed it before but was a decent price and with 20% off eveything at opieoils thought i might aswell try it .

as richwig83  says a thicker oil on a high preformance car will heat the oil up more ... thining it down to 5w30 in essence.  :happy2:

Not quite. The engine oil should be the same temperature but at running temp. the 5w40 will remain thicker than 5w30.

not sure about that pal, I've done numerous 1/4's, 6 trackdays, you get the picture and it still uses very,very little. I just think some do, some don't  :happy2:

Fair enough, you're probably right, I just liked the wording they used  :laugh:
Mines never used much oil really and over the years it's been driven both hard and gently

I have had several brand new cars over the years - Golf GTi 16v, Cosworths, Scooby sti's, Honda type R's, lotus Elise etc. I never ran them in for more than 100 miles and none of them used an appreciable amount of oil.

A pal of mines Nissan saloon thing is driven like miss daisy on a fuel economy run and uses a liter every 1200 miles. Must be like a 2 stroke!

Alex recommended the 5W-40 for mapped engines which work harder than VW standards and hence would benefit from a different oil. If the car is standard, then 5W-30 is fine.
