VAG Oil Backward Incompatability?

Appreciate some help here with a post on another forum. I like to come across as a know it all but unfortunately I know *-all. Here's the post "Hello all. I'm really hoping for some feedback from people familiar with the Nissan Cefiro and engine oils. I bought some eni brank i-Sint tech 0W-30 synthetic engine oil for my 2.0 L Nissan Cefiro. When I got home I found the manufacturer says it is only for certain VW engines and NOT allowed for use in all engines. I don't know if this is just standard CYA or if other engines really can't use it. Does anyone use this oil in the Cefiro or know of people who do? Manufacturer's info: http://www.enischmiertechnik-datenblaet ... 1008_e.pdf "eni i-Sint tech 0W-30 is a modern fully synthetic engine oil with lowered HTHS Viscosity, which had been especially developed for vehicles with gasoline and diesel engine of the VWGroup starting model year 2000 with prolonged change interval including pump-nozzle engines with prolonged change interval. " "eni i-Sint tech 0W-30 had been especially developed for the engine generation of the VWGroup for vehicles starting model year 2000 with prolonged change interval including pumpnozzle engines. Due to the prolongation of the maintenance interval oil changes up to 30.000 km are possible for gasoline engines (VW 503 00) and for diesel engines (VW 506 00/506 01) up to 50.000 km respectively max. 2 years. " "This special engine oil is not allowed for the universal application in all engines." And here’s my initial smart-arse response “I don't buy synthetic oil, but if I did, I wouldn't buy this stuff, because:- (a) I've never heard of it. That might just be my ignorance, but that's the ignorance I have most readily available (I don't have a smartphone). (b) the logo looks (suspiciously?) like Agip's in style (c) I don't do many miles, so alleged reductions in fuel consumption aren't a primary concern to me (d) it says on the bottle that I shouldn't. Its quite difficult to get any specific information on oil, since its all proprietary and secret. (They won't, for example, usually tell you how much ZDDP is in it, which is of concern to me) so when they fairly specifically say "don't use this stuff" that's perhaps worthy of some attention, though I'd guess that instruction is lifted from the VAG spec. and doesn't originate with the manufacturer of this stuff. Id guess the implication is that the lower HTHS viscosity might result in higher wear rates in wider-tolerance engines than the stuff is targetted at, because the crankshaft (for example) will tend to rattle around in the bore some. I'd take it back for a refund/credit note and buy something mainstream with it. If I couldn't get a refund I'd cut it with a high proportion of the highest viscosity oil I could easily find. I'd probably use CPC straight 40, which is widely available and cheap. You'll probably want to use a synthetic but you wont find one in a straight grade. IIRC Costco had 15/50 Mobil 1 at a fairly good price, though I don't know much about synthetics or their local availability. http://www.mobil.com/usa-english/motoroil/files/mobil_1_product_guide.pdf (couple of years old, so may be out of date) Incidentally, if you get any responses to your "has anyone used this in a Cefiro" enquiry they are unlikely to tell you anything useful unless it was either (a) completely disastrous (unlikely) or (b) they have done a before and after series of oil analyses (VERY unlikely).” I’ll forward and attribute any useful responses to BITOG. Thanks in advance.

Isn't Eni the parent company of Agip?

Thanks for that. If that's true, then this stuff probably isn't snake oil (which I'd suspected it was) and the reason for, and extent/seriousmess of the "backward incompatability" in the thread title (which was the OP's concern) becomes more central. Before I finally give up on dissing this oil though, I'd add that (e) 20,000 km longer on the oil for diesel engines does not seem (to me) to compute. I'd expect diesel engine oil to degrade/get contaminated quicker, and therefore be changed sooner.

Yes it is. You can use it in a Ferrari . http://www.superformance.co.uk/a-348/oil.htm
The brand, but perhaps you shouldn't use this particular stuff, which is 0-30 weight (with a low HTHS viscosity), while the stuff recommended in that link is 10-40 weight. And I'm told those things are expensive.

Seriously, dude. if yannis buys me a Ferrari I'll use whichever Eni oil he recommends, even if it's a bit on the thin side.

Hey , Dr.A.E.Haas wouldn't sweat using this stuff in his Enzo. Honestly, i meant the brand .

Easy come, Eni go? But seriously folks, what's the basis (if any) for the caveat about using this oil in non-approved engines? Incidentally, I don't think the OP has said how old his Cefiro is, but a bit of casual Googling suggests the recent V6's, at least, are frighteningly (to me) advanced/complex and maybe not so low-stressed. All that gubbins and they can't be bothered to fit a 50$ prelube system? Go figure.

[quote=Ducked]Easy come, Eni go? But seriously folks, what's the basis (if any) for the caveat about using this oil in non-approved engines? It's a 0w-30 ACEA A5 / B5 engine oil, forget the VW specs as they don't apply to your engine/service regime. VW longlife oils ( VW 503.00, VW 506.00, VW 506.01) are designed for their engines to do long oil change intervals. Does the oil meet the requirements of your engine in your climate?

Does the oil say API SL or above, or ILSAC GF-3 or above? If so, it would be the right oil in a Nissan engine. No Maxima in the USA I have ever seen is incompatible with 5w30 and doesn't need a proprietary specification, API or ILSAC is enough.

It's not my engine, but that's what the OP was trying to find out.

It says ACEA A5/B5-04. That (apart from the VW specs) is the only spec quoted on the website. Since it also says “This special engine oil is not allowed for the universal application in all engines. Please observe the manufacturer’s specifications when selecting products” the OP has decided to take it back for a refund. Seems reasonable.
