1.8T

[oprn]

I am looking at buying an Audi A4 with a 1.8T engine. Anyone had experience with these? Does VW state in the owner's manual that they require premium fuel?

IMO, the 1.8t (up to 2005) is arguably the best engine that VW has ever made. The biggest issue that it had was “sludging” due to manufacturer suggested 7-10,000 mile oil service intervals, and then the engines not getting the proper synthetic oil put in them (even at the dealer).


The engines ran hot enough internally to “cook” the oil, which built up as carbon on the inside of the block (like cooking oil in a frying pan.). Most of the engine failures were due to this carbon coming off (usually after a quick lube type place upsold an “engine flush”.), and blocking the oil pump pickup screen. This obviously led to oil pressure loss & subsequent failure of the engine and/or turbo.


Past that, most of the other issues (check engine light) were vacuum related.



They do require premium. You can run low grade, but the fuel economy plummets & any $ saved is lost in the difference of mpg.

I would agree with that assessment. Don't forget to maintain the timing belt. Too early is better than too late.

Come to think of it, too late is not good at all.

This is a 2007 with 48 K miles so hopefully still ok. I am a 3000 miles/oil change kind of guy, always have been.

I have to agree also. If I ever end up with one, the first mod would be an Oil Cooler w/ a thermostatic sandwich plate.

The 2.0t FSI engine is horrible, the 09+ 2.0t TSI engine is far worse.


The FSI regularly wiped out camshafts due to driving the high pressure fuel pump with a flat tappet.


The TSI shits timing chains around 70,000 miles, and then the piston rings/pistons start their oil consumption issues starting around 50,000. 1qt oil/1,000 miles is “within spec”.

The FSI is an extraordinary engine…. When compared to aTSI.


The 1.8t is a far better engine.


I wouldn’t worry about the high internal temps, it helps them run more efficiently. Just keep the proper synthetic oil in it & change it out every 5,000 miles.

What about the CVT transmission? Any issues with those?

Although CVT's have been out awhile [I believe the Subaru Justy had them first in the USA, mid 80's] they have improved. They are basically a throw away transmission that cannot be rebuilt. Getting a used one is not a good idea because those are probably just as bad as the one you are replacing.

It's one part in the car that will total it real quick.

[Butcher]

As for the oil cooler, I believe the stock V6 coolers are similar but larger. With the right stand pipe, I believe it is a simple swap.

There are two camps about oil cooling. Those that love air and those that love liquid. There is no right way so pick you camp and be happy with it.

[ps2375]

I have both on my car, liquid is good for warming the oil and the air cools the oil. If the liquid coolers were bigger to give more time for heat transfer, I'd be good with that, but for the actual diff in temps between the cooling media and the liquid to be cooled, the amount of time the oil is there just doesn't seem to cool it enough for me.

[TDCTDI]

Oil temperature is not the problem, the problem is where the oil comes in contact with the walls of the block & cylinder head that causes the oil to burn. This only happens with conventional oil, not the synthetic.


I believe that the CVT transmission was only for front wheel drive models, I gots two of them on the floor, it was cheaper to buy whole wrecked cars than getting an engine for one.

Not trying to convince anyone which is better, but if the oil is at 130C and the coolant is 90C, I would suspect the oil to come out cooler. If the oil is at 60C and the coolant is at 90C, then I suspect the oil will come out warmer. Getting the oil at operating temperature sooner does not really have any drawbacks.

As for CVT's, I agree, they only came in 2WD that I know of. Good thing Audi makes a lot of Quattro's.

[oprn]

Well I missed out on that car.

I will see what comes up next and shoot for a 1.8T or a 2.0 FSI then in a Passat wagon or an Audi A4 wagon. Too bad VW never put the standard gearbox in those.

I'm fairly certain I've had a 1.8T 5spd passat wagon before..
