2.0 JTS engine oil confusion

Hmm, I may have given myself a “situation.” I’ve only had the GT about 6 weeks and have had to top up the oil. Its got a 2.0JTS engine and what I didn’t realise is the handbook specifies 10w-60 oil.

Without thinking I used the oil left over from my 1.8TS, 10w-40. I suppose I just assumed it would be the same oil as it’s a very similar engine. I suppose I should say I have no idea what oil was used on the car at its last service, have to assume it was 10w-60 I suppose.

Problem is, the handbook says you shouldn’t mix different types of oil. The car seems to be running fine though, if anything better than before (the oil was very low). Should I worry?

AFAIK the oil spec was changed to decrease oil usage, you will be fine so don't worry.

What i would worry about is the fact you let the oil run "very low" the JTS engine like the TS does not take running with low oil levels very well, check the oil weekly and keep it topped up to max on the dipstick, it will save you from a very big bill for engine failure caused by running on low oil levels

Yeah fair point and lesson learned. Many thanks for the reassurance.

In my defense I only got the car 6 weeks ago from an independant and made the fatal mistake of assuming they would have topped it off. Yeah I know......"never assume as it will make an *** out of U and me"

When I picked up my car the sump plug was litrerally finger tight.

I changed the oil as soon as I got home after picking it up as I had no idea when it was last changed. It was a good thing I did otherwise that could have been terminal for the engine, and not good for any motorcyclists either.

Spider 2.0 JTS

Mixing oils is okay, but it's recommended to put in the same grade oil according to oilman. He seems quite knowledgeable about different oil grades and their characteristics. There are many threads on this topic. I have a 2.0 JTS as well and I've been using 5W-40 in my engine. I've been using it for almost 7000km without any problems. knock on wood

I had this issue after a first service on my new GT JTS - my local dealer put selenia semi synth in it!

This was a direct contradiction to the handbook - which they told me to ignore, so I spoke to alfa uk who said that semi was ok - still not satisfied I emailed alfa in Italy directly and got two responses - one telling me i should only use fully synthetic selenia racing ( i cant recall the rating) then about 10 mins later a phone call from my local dealer apologising for the bad advice and offering to collect my car and change the oil & filter immediately to Selenia racing, if it was convenient. I have to say I was very impressed with the speed of response but applaud that Alfa UK and their dealer network are clearly buying oil in bulk that is fine for most of the Fiat range and sticking it in everything!

A friend of mine who is an Alfa Technician says 10/60 in the JTS is very important for camshaft life, as the top end gets a lot hotter than the old TS - not sure how true this is - but I have no reason to doubt him!

Some 10w-40 in with 10w-60 isn't really a problem as it will burn off fairly quickly (one of the main reasons the car uses a 10w-60). Then when it needs topping up, put a 10w-60 in.

10w-60 oil

Engine flushes and oil additives are no good for engines, just use good oil and service the car as instructed.

You don't have to use Selenia, there are plenty of better 10w-60 oils out there.

Have a look on Oilmans site for a few examples.


Personally I don't rate Selenia very highly at all.

... Yes

The GT Owner's Manual is VERY clear.

10W60 for the 2.0JTS & 3.2V6

10W40 only for the 1.8TS

There are some very good 10W60 oils around now too.
If you can find it the Redline 10W60 is probably the best:
Red Line Synthetic Oil - Motor Oil - 10W60 Motor Oil

it's been 5 year that i use Selenia Sae 10w-40 in my 2.0 JTS and the Sound of the
engines is getting noises every year so i decide to use engine treatment Liqui moly Mos2
ิำbetter but after 6 month the noises come back again with the Warning motor control fail go to dealer
the alfa dealer check and seem to don't know but told me to change Coil there are 4 Coil but only need to replace one of them the warning show but the car still run normal little shake but run ok can i just choose to ignore the warning and just go to alfa dealer and Delete the warning and try 10w60motor oil this warning has show up one a month i think maybe because of the engines treatments Mos2 not sour
i think i need to use Engine flushes mos2 out and aver use it again i know that use flushes is not good for the engines but i need to get the engines treatments mos2 out and fill in with new oil
or don't use flushes ? but i think Mos2 will not come out with the old oil (><)
if is not about the Engines treatments Mr Rhogan do you have this kind problem with your 2.0 JTS engines

In the Fiat community the Millers 10-60 is very highly rated, especially for turbo-charged engines..........

Beer,

If you have a JTS, you need to use a synthetic 10W60 oil, especially in Thailand (since I guess it's pretty warm there.. hot weather places more strain on the oil). There's probably no problem using 10W40.. but for proper protection.. your engine wants 10W60.

I wouldn't bother flushing the engine, just drain the oil as normal. Engine flush uses kerosene to shift any gum or sludge in the engine.. but if you use synthetic oil (10W60) then these have a lot more detergent in them than older types of oil, so they will shift gum and dirt better than engine flush anyway... and because they don't break down so easily and they're better at absorbing any new contaminants.. they will prevent new gum or varnish from forming.

Oil additives are just viscosity improvers. They can boost old oil and restore it to how it was like when it was newer.. but as before.. a synthetic oil is better at keeping its condition (viscosity).. it doesn't break down like older types of oil.. .so it doesn't need a viscosity improver. Just drain your oil as normal.. and put some sythetic (10W60) in there.

Your coil problem is probably not related to the oil.. but you could have oil leaking into one of the spark plug wells (either spilt during fill-up or a leaking rocker cover gasket).. so make sure the spark plugs are not drowning in oil. If a coil is worn out.. then it's not toooo expensive to change it.

A Bosch injector is around £100 (US$150) but you can find them a bit cheaper than that... maybe £75 if you look around.

There might be some other brands available too, which will be cheaper than that, even if they're not as good. I guess even a cheap one will last 4 or 5 years. Bosch is the OE manufacturer so there's no need to pay extra for an "Alfa" part, if a Bosch one is available.

Shop4parts selling JTS coils at £63 + VAT and I think they will post it to Thailand.

Fiat & Alfa Romeo Parts Specialist.Alfa Romeo 156 Mk2 (2002>) Ignition Coil

You shouldn't have to pay VAT (sales tax @ 20%) since it's going abroad... but Thai' Customs might touch you for local sales tax on import, depending on the value threshold.
