Hi,

Is this suitable for my engine (1.8t)

10w40 Part Synthetic

I know 10w40 is but I cant find any info on part synthetic

[mac456]

is it just the same as semi?

You need fully synthetic for the 1.8t mate.
Best bet is quantum platinum 5w40
Part number - ZGB 115 qlB 005 11
Can get 10l on eBay for £50 posted iirc

I use Quantum platinum 5w40 all ok in my 1.8t, would not be happy with semi synth

I used Quantum Platinum 5w40 Fully synthetic... meets VW spec 502.00 - 505.00 - 505.01

and is only around £28 for 5L at VW dealership

car plan gsf 5w40 is just the same as the vw stuff, but cheaper.

in the last 10 years i must've done over 200,000 miles in mk4's of various levels of tune using a 10w40 semi synth and never had issues. But then i am rather OCD about doing oil changes every 5k.

what do you recomend for 1.8t mate as so many different answers

10w40 semi is good too. As long as you change it regular there isnt an issue. Just donk get 20w50 mineral sh!te.

oh i never make recommendations when it comes to oil, too many forum "experts" have their own strong opinions on the matter i will simply say that both 1.8Ts i've owned in the past were fed on 10w40. Both were highly tuned (and spent many many hours on various dynos) and I never had any oil related problems with either of them.
