I have a nearly full 20L tub of GM's finest 10/40 Semi in the garage, that was planned for the 3.2, this ok to go into 1.4 Turbo petrol lump?

He knows SFA about cars. Best to ask STMO.

[Jimbob]

I'd suspect not, what spec does the book say?

Await expert input, but I wouldn't run any turbo car on semi-synth. For example a lot of GM era saabs suffered sludge build up which was, in part due to oil breaking down when it passed hot spots in the engine (particularly around the turbo). Its notable that the Aero models suffered less with this, due to it being mandated that they used fully synthetic oil.

You're very astute, Opti. That Mark fella always PM's me for advice before he posts.

Interesting, I did not consider the little 1.4 to be a 'performance' type car you normally associate with Turbo's. That said, Vauxhall thought it would be good idea to but a 'Turbo' badge on the back of a mummy bus.

Ah yes the book, should read that. 

But as Fuse19 is usually better than the book..... 

[tunnie]

Ok, so no, should be: SAE 5W-30 or SAE 5W-40.

Damn. Got around 15L of oil I don't have an engine for now

[Diamond Black Geezer]

If I was nearer i'd be tempted to make you an offer for the set of springs and the oil... Fuel there and back sort of offsets the price advantage, especially at my mpg! 
a) just bought a set of sachs for the rear I still havent fitted yet
b) just spent up on a new battery that's looking like a waste of money (old battery wasn't the problem, possibly was down to a relay) so that's skinted me!

heart says 'yes' wallet says 'no'

I see you have Coventry as location? Not sure when I'm going to Brackley next (trips are rare) but I could drop it off at that angry little short blokes house? Might be easier to collect?

That's only half the story - what spec does it want? (i.e. ACEA A5, API spec, brand specific spec etc) That's just as (if not more) important than the viscosity..

Does it matter that much in petrol? Thought yes for diesel with DPF etc.

Depends on the petrol but yes, it can do - direct injection (quite common, now) requires specific oils, for example, which deposit less carbon in the intake (since there is no fuel washing the intake tract anymore, they tend to coke up very quickly)..

I'll check the book when I get a chance, it's not due an oil change until next year though.

Indeed, modern highly strung petrol engines are just as prone to this as modern highly strung diesels.

A side effect of direct injection and overcomplicated emissions control systems aka breathers

[biggriffin]

It's a GM product, use dexos 2  5/30,

Next.

That's something that could work, aye  Heading back to NE Lincs for Xmas, but that's not really nearer Surrey! PM me if anthing's doable - obviously don't want to muck you about, either, if anyone else can just take it off your hands.

Probably not, the turbo needs a pretty high spec oil, which version of 1.4 is it? (year and bhp is a good guide)

Actually, that's not the real drive for a different oil type for direct injection.

Its more to do with small quantities of oil getting past the rings (as it does on any engine) causing detonation of the fuel the second its injected...........ask Ford, its what has driven massive warranty issues on the Ecoidiot engines

That too - not that BMW/Mini/Peugeot admit to it. Then again, the engines usually choke themselves to death well before that when the intake tract is about 20% of it's original CSA..

2016 Plate, 138bhp I think.

[aaronjb]

This is a Zafira, right?

The manual says Dexos 2 (what Biggriffin said) or, if unavailable, 1ltr of ACEA C3 until the next oil change.

Here you go - tis what I use in the BMW & MINI, Dexos 2, ACEA C3, BMW LL-04 etc: https://www.ebay.co.uk/itm/20L-5w30-BMW-VW-SYNTHETIC-Oil-VW-502-505-01-BMW-LL-04/123670115779

Yes, the more recent Tourer variant. Although I see on the F/L they dropped the 'Tourer' brand.

Thanks 

Might take a while to go through 20L of the stuff though! The ACEA C3 appears a Vauxhall general requirement, as that was on the spec for the diesel Tourer as well.

In other news found out recently, they have pulled the plug on the Zafira range. 

[aaronjb]

Doesn't take me too long to get through 20L - ~8L in the BMW and ~4.5L in the MINI every six months
I'll pick up a 20L tub for the RRS at some point, too (different spec).. that's just two oil changes (10L each!)

So far, no complaints about that oil other than how slowly it comes out of the cheap barrel tap I bought.. I think I felt my beard grow while I was waiting for 4.5L to come out

[edit] That was from the 2014 Zaffy manual, btw, because it's what I could find online at Vauxhall..

[aaronjb]

Keep your eye on this, too: https://www.eurocarparts.com/p/gulf-formula-gx-5w-40-engine-oil-20ltr-521774135 - with the discount code, it's down to £38!

[tunnie]

That's very reasonable, I have to make some room in my much smaller garage storage area now. Before I can add more stuff in, need to off load all the old Omega stuff I have.

To clog the inlet then they are suffering from heavy breathing, that's an engine design issue more than anything!

Anything I should look out for on the 1.4T?

[Doctor Gollum]

Bit late now... 

[Marks DTM Calib]

Anything I should look out for on the 1.4T?

Not on that derivative no, the later one (not used on the Zaf as it turns out) is direct injection so a little more sensitive, the one you have is a larger version of the chain driven cam 1.2 used in Corsa etc plus variable valve timing and a few other bits.

Regular oil change is king on them, then they just work and last

Yes regular changes, to keep that chain lubricated. 

It's use will be 95% town, rarely going on high speed runs. Although when given chance I will take it on long runs, Wales for example at Christmas.

I plan yearly or 5k changes, that would be sufficient?

Can I be cheeky and ask the same question about the 1.6 A16LER (2008 Corsa VXR)? Friend of my fiancée just bought one and I'm sure I'll be the first person to hear about it if/when it goes bang!

Small block engine (family 1), been around a long time (distant origins in the old 8 valves from the Cav etc).

Generally no great issues, its the M32 manual box that was more problematic (although this had a big revision in around 2014ish which increased the size of one of the bearings, re-enforced the end case and improved lubrication......this end plate can be fitted to the older boxes to)

[aaronjb]

Perfect .. thanks! Here's hoping I never end up knee deep in bits of Corsa, then

[TheBoy]

Yes, the more recent Tourer variant. Although I see on the F/L they dropped the 'Tourer' brand.

Since the facelift 2 or 3 years back, its officially Zafira-C rather than Zafira Tourer.

[TheBoy]

I always use lots of 10W40 semi.  But as its so cheap from dealer, delivered, its not worth getting from anywhere else.
