Just wondering what oil everyone is using in their 4ages and what they have experienced in use,ie,temp,pressure readings and failures.

I had semi synthetic in and then went to 5/30 mineral oil.only thing is the oil tends to run back when stood for a few weeks and I have to crank the engine for a few seconds before switching the fuel pump on,bl@@dy thing fires too quick for the oil to get round .

pretty normal behaviour for used 4age's. even my 120v does that when it's been sitting for a while.

I have used 10w40 trhoughout all the 4age engines that I have used in the striker, I Once switched to castrol magnatec full-synth 10w40 and the engine died within 200km's but that was at a very high milage.

I've always used Vauxhalls fully synthetic bought via the garage I use, its in a grey 5 litre container for about £17! ( that might be trade though). I think that stuff is 10W40 too.

Thomas, yep old engines don't like the thin stuff as the tolerances have usually gone rather lax.

Must admit when I was a self employed mechanic I kept three oils only,used 10/40 for multi valve engines,15/40 for older stuff and diesels and V8's and semi-synth for the oddball stuff like BMW engined Range Rovers etc.

Come to think about it thats what I keep stocked in the workshops I run now as well!
Only use the semi on Mercedes Econic lorries as they are a bit fussy,must be a german thing.

I think I'd better get some 10/40 in.

I also had the bottom end go with semi synthetic in,although it was down to a crap sump that I copied and should have known better.I still dont like semi or full synthetic for these engines but the Aussie experts seem to advise to use it.
I must be old fashioned but I cant get into my head that oil that looks like water can stop metal to metal contact.
