OR....it could even be a typography error !!
Doubt it, I'm picking up my TA tomorrow which is a very recent build so I'll see what's in the manual and report back
Thanks I'll check it out. The car was built to my spec and ordered early December, I was told it was scheduled for build 1st week in jan so I'm presuming it's a 2014 car, got here very quickly all the same, all will be revealed tomorrow!
Thank god! I was waiting for a comment from an expert. Now one comment from bgunn and we are in the money!Ok, I'll chime in with my take on this.
The basic difference between 0W30 and 5W40 is that the former is thinner at all temperatures.
The main benefit of using a thinner oil is reduced engine friction, so thinner oil equates to better mpg and lower emissions. Those who remember the history of the Mk3 Panda will know that FIAT reduced the 'official' CO2 figures by around 20% to get the later cars into the £30 tax band, essentially by doing just two things; using a thinner oil & fitting narrow ecotyres.
So a thinner oil means lower emissions & better mpg, both of which are good, but there's another consideration & that's engine wear.
Thinner oils are less effective under load, particularly under high pressure loadings (which is why the components of the car that are subject to the highest point stresses, the gearbox & differential, use much thicker oils). Also, thinner oils reduce oil pressure, which can be compensated for by reducing manufacturing tolerances &/or increasing oil pump capacity.
I should also mention that thinner oils circulate better when the engine is cold, but run off bearing surfaces faster when the engine is stopped.
So FIAT's move to 0W30 is almost certainly motivated by a desire to reduce emissions for Euro6. Have they also increased oil pump output or changed bearing tolerances? Who knows.
Manufacturers often make changes to manufacturing tolerances and specifications without making a big public announcement of the fact. Using the wrong specification of oil for your car without good reason when they know what they've done and you don't would seem to me to be rather foolish.
That said, I've given some thought to running a very lightly driven 1.2 on 0W30 in the winter when the benefits of better cold circulating performance and reduced friction might outweigh the disadvantage of the reduced lubrication protection of the thinner oil. But I've only thought about it and haven't tried it yet.
The one place I'd definitely not use a thinner oil than that specified is in a car driven hard in a hot climate. If you're Ahmett and you think this comment may be aimed at you, you just might be right .
I'll make one prediction, though; now the TA fleet of otherwise identical cars have different recommended oil specs depending on the date of manufacture, there are going to be a lot of cars which are serviced using the 'wrong' grade of oil.
Funny though I was looking at the Mini Cooper S drivers manual, and they were saying you can use the 0w-30, 5w-30, 0w-40 and 5w-40 depending on your type of driving and all 4 specs are covered under warranty! What do you have to say about that?
And on that note, I'm not a fan of using S/S on turbo cars.
So about the oil then...........I asked my dealer when I picked up the car today as to what the actual build date was and he confirmed it was week 51 so it was 2013 by a hair. The manual says oil should be 0W-30 ACEA C2 GRADE FIAT 9.55535-GS1 classification for 65, 85 and 105 TA engines. So to add to the confusion my car is 2013 but recommends 0W-30. I haven't got the VIN yet but should have it tomorrow so will check against the Fiat site and see what it has to say.
Yes, absolutely, make sure you thoroughly check the configurator with the car VIN and if necessary, check again with the dealer because if you do need to top up and you don' use the correct oil in respect of warranty, you risk being at the mercy of Fiat. Your situation sounds a little ridiculous, there shouldn't be any ambiguity in terms of the car's horsepower or the lubricant it is supposed to use. VIN code is on a plate on the boot floor, so you should have it anyway.
Ok so it's definitely an 85hp TA, driving it again today it's obvious, called out to the dealer today to collect reg docs and had a look in a new 1.2s, in the manual wallet was a booklet on the 65hp TA! Bizarre! They must go in to all the packs as standard! Anyway relief all round and the car has exceeded my expectations so really really pleased. I only have a chassis no on my docs - is this different to the VIN? Anyway it dident work on the fiat site so will check the boot floor for the vin and let you know.
Chassis number and VIN are exactly the same thing.
I emailed the dealer in the end to ask them. Since the salesman had stated over the phone that I should put in what the manual advised (0W30 C2).
I wrote that I was confused and stated that there was a lot on conflicting info and that I didn't want my warranty at risk. Manual states one thing, Fiat iPhone app states another etc....
Anyhow, the head service technician got back to me and stated that only 5W40 C3 oil should be used in the TwinAir or MultiAir engines.
hmm, you're in the same position as me - that niggling doubt as to what actual oil is in the car? Can we safely assume 5W40 despite the manual?
I honestly think if you are that concerned you should telephone Fiat Customer Services, or email them and ask for their Technical department, give them your VIN and get them to put you straight on the issue.
If you want to stick with your own dealers advice, I would absolutely recommend you get a written statement from them, signed by the dealership manager that what he has advised you is correct. Then, if it all goes horribly pear shaped later on, then you have some come back. I think also that it would be horrible if they serviced the car and put the wrong oil in and something went wrong. You need an absolute definitive answer to put your mind at rest.
Guys you are acting like the service ppl know what they are saying! It seems like fiat made this change without informing anyone or anyone listening to fiat! Fact is they want 0w-30 on their new ta cars so use it! U think fiat are efficient enough to update their iphone app real time?
Anyway as jrkitching wisely said, this oil type change is going to create a lot of confusion!! So every man for himself use which oil you feel comfortable with and make sure you ask what type of oil was used so you top oil up with the same spec!
