I use 5w-50, but after hard burnouts realize that 10w-60 will be better choice. And 0w-40 for the winter.

 

Castrol Full Synthetic 5W-40 is VW 502 and 505 approved and specifically made for VW/Audi. Also a personal choice against Exxon/Mobil (Mobil 1 oil) in general.

 

Mobil 1 0w-40 full synthetic w/ OEM filter (for my 03' 1.8t). This is what's also recommended by my dealer.

I've used Castrol before in my old car w/ no problems, & have also used Chevron in a pinch. Just stay away from Pennzoil... heard way too many issues with them.

DavidL, what's wrong with Mobil 1?

 

Used Mobil 1 in the past, engine didnt seem to like it very much... Now using Castrol 5w40 engine loves it... Also have used Valvoline 5w40 with good results...

On more than one occasion Ive actually been recommended to run a non synthetic oil in my 2000 1.8T.

Im in the process of using Auto Rx to clean out the sludge build up (the downfall engineering of our engines) and when its complete I was told its better to stay with a non synthetic because of its properties

I was also told that syn runs colder but it holds in the sludge that will accumulate over time

any thoughts?

 

Don't like Mobil for polictical reasons. There is nothing wrong with their products that I know of.

 

In a turbo car you want a good synthetic, if you want a synthetic that is really good at cleaning use Shell... A synthetic will not necissarily "run cooler" but it will stand up to the high temperatures better... So would you like a conventional oil to reach the temperatures in which it starts to cookin the turbo, or run a synthetic that will stay fluid...

I have heard running a conventional oil in the V6 is perfectly fine, I dont due to the higher temperatures my oil experienced (250ºF at times) but if I did not hit such high temperatures I would use a conventional oil later in the engines life (most likely ahigh mileage oil)... In a turbo car I have always used Synthetic due to the heat produced by the turbo...

Anything that is VW 502.xx spec is fine to use. Fully synthetic is a must with the 1.8t. Whoever says not to use full synthetic with that engine should be burried up to their neck wherever scorpions breed.

 

haha good tip 1.8Tee

I agree that with a turbo synthetic should always be used ... during the auto rx cycle I can only run "dino" and not a synth

but when I am complete synthetic is goin back in for sure
