Best Engine oil for Volkswagen Jetta

After oil change where I previously had 5W-30 with valvoline dino, I changed with a different brand 5W-30 (Peak brand). Ticking noise started immediately from engine area usually only after it got up to temperature. So I pulled out a quart from the diptube with my suction device and put in a quart of 10W-40. Almost immediately PROBLEM GONE.

Leichtlauf is great, I've noticed smoother overall operation in my 2.0 TSI Jetta and GTI since changing from dealer Castrol.

I will also use a zero weight synthetic like mobil one.

After using German Castrol on my mkv back in the day my mpgs went up significantly.

Amsoil 10-30 was my choice on my 200,000 mile 2001 jetta + i changed @ 10,000 usually 4 to 6 months. car was chipped etc, about 300 tq + 275 TQ with a KO-4 + APR tune etc.

Best oil IMO is Castrol 10w40 high mileage part synthetic, usually good specials at local auto parts stores and Walmart.

I've been alternating between the OE Castrol (with the free maintenance) and Pennzoil Ultra Euro 5W-40 (502 compliant and recognized/certified by Audi/VW) in 5,000 mile intervals. I've had both tested, and the TBN is higher on the Pennzoil and the viscosity always perfect (Castrol tends to read thinner than 5w-40 on the samples I've sent in for analysis).

They were using the wrong oil- Shell 0-30, and it was clicking pretty loud when cold. I got the oil change kit from Duetche Auto and put in the Luqimoly. What a difference. I cant recommend it more. You will love it.

Castrol Syntec 5w40 is stout enough for the 10,000 mile oil change.

I just found this thread. I have a 2014 Jetta 1.8t with 107k that I bought for my daughter two years ago and it burns through a quart of oil about every month. It dropped cyinder 1 similar to what the other person experienced, but new plugs and ignition coils solved the problem.
