The T5 Oil Change....

[JamesT5]

I think you'll struggle with that a little that's why manufacturers have their own recommendations, really only the latest engines should have that grade of oil tbh. Now you know how easy it is to change the engine oil and filter when you change it again opt for a decent 5w30 or 5w40 and change it frequently, I do mine no longer than every 3,000 miles and that's both the 850 and the 940, some would see that as too frequent but it does no harm at all and for the cost is the best preventative maintenance you can ever do.



I doubt it tbh... Will probably thin right out with heat.

I agree about the frequent oil changes, it's something I really want to do more often and if I'm buying my own oil and filter it's probably no more expensive than taking it to National.

James, here's a link to a thread I posted a while ago. My opening post contains some very interesting reading on oils.

I used the same flush on mine last winter and it worked very well (also causes the watery slick on the surface when draining). But if you value that engine, make sure the only driving you do is to the nearest halfrauds to buy some Mobil 10/40 semi-synth so you can drop that 'orrible stuff and put the right stuff in.

I also have a high mileage engine, as you know. I did a bit of research into it and the best thing for them is pretty much what it's always had - 10/40 semi.

Nice to see you back by the way mate

Indeed! I think it's great to see you working on your car and attempting things yourself and it sounds like you've got great intentions and have done a great job but if it were my car I'd probably drop the oil out at the next opportunity and get something a little thicker. MRP puts across probably the most valid advice on oil choice as he's got a car of similar age and mileage to yours etc etc and has been running 10w40 for sometime now. You'll probably find the car will feel just as good on 10w40 as it did on the 0w20 if not better

Interesting advice coming through on here and I did read that article on another website that MRP has put a link to, above.

Considering what my engine has been running on (i.e. 3 + litres of black sludge), I think what I have running through the engine now is better than that. However, reading the flood of replies that suggest I should use a thicker grade of oil, this I think I will do on my next oil change, perhaps I'll do one slightly earlier than intended, say in 3000 - 4000 miles from now and go from there.

I think that would be seen as a suitable compromise to rushing out and dropping oil I've just paid out for.

[M-R-P]

Not wanting to come across as having a go James, I'd like to think you value my opinion. So, when I say I don't care if you sold your relatives to buy the stuff in your engine at the moment, it'll kill it before 3000 miles....

Don't think badly of me, I just don't want to see you scrap your car.

[merc85]

if you did drain it out, look at it another way, its cleaning the internals even more? expensive way of doing it. but at least its lubricated everything up again after the flush

[t5 pete]

Dont say we didnt tell you and good luck insufficient oil grade can do alot of damage in 3k if it gets to that hopefully it will get to 3k

Please change that oil before you drive the car any distance, or the only place it will be going is the scrapyard.

sounds like your engine has a hard life and its going to come to end with that oil. the big ends will be knocking in no time. do it once do it right.

I've been recommended 5w30?
Should I be on 10w 40 then?

Ive got 5w40 fully listed and 10w40

[Nealevo]

Well this is going to end badly.... Another car for MRP to trawl over in the scrapers!!

i use 5w40 in mine.

Me thinks another oil change is on the cards then, bugger.
Good job my car hasn't had a dam good hiding for ages.

[AndysR]

I was running 5w30 in my 850 and when the engine was stripped for the rebuild there were no reasons to suggest it was doing any damage what so ever so you will be fine to continue using it provided your engine is in fine fettle

There is so many different oils and spec's tbh. Its best to select a Brand of oil you like to use, then look up what they suggest for your vehicle as there is so many different spec's between manufacturers , this also changes as the cars get older and oil's become more advanced.

For example using this : http://www.commaoil.com/products entering your reg ie my reg it says 15w40 Comma

Using this : http://www.morrislubricants.co.uk/lu...or/default.asp it says 10w40

[JUDGENINJA]

5w40 full synthetic for me... I didn't even know they did 0w20... What's that for a 2stroke?

What ever it is, it doesn't sound good. Whether it'll blow your engine up I'm not sure, but an aged car would usually go for lower grade 10w40 rather than higher..

James... I might heed the others advice or be a rebel like me and end up with a car like my 850that hasn't had an engine in for 6years!!

I`m thinking of going for 5w40 too,have 5w30 in it at the moment more as a flush oil tbh

Well we have no engine warning lights/rattles or smoke so guess I'm safe. The oil has cleaned itself a few times with the changes.
I tend to use ac delco or Morris but can't remember what it had last. I'll check my receipts methinks.
Thanks boys, I was going to hit the roof with my mate who owns my motor factors.
I'm still arguing the blue/pink anti freeze dilemma!!
I now run pink. Lol
