Engine oil VALVOLINE or Mannol

VW recommends 505.01 for fixed service at 15k Km or 507.00 for flexible service at 30k Km. Since our driving condition is harsh, I usually cut those Km in half. Since you were pushing 505.01 at 12k I would recommend you use 507.00 5W30 LongLife for 15k to 18k to be on the safe zone especially if your runs are on highways. I’d highly recommend you check oil from Mannol 507.00, I’ve been using them and they are solid choice. It costs under 3.5k for 5L. You can fill 4.4L at change of oil and top up 200ml at 4,8 and 12k interval

If you do research oil analysts here in this sub, Valvoline comes out the best.

Using high mileage oil (additives to make gaskets swell just a tad bit), used to burn almost a quart between 5k miles but now it's maybe half a quart.

Looks real good. Valvoline R&P is in mine now.

Valvoline Restore & Protect oil, stat!

I do like Valvoline R&P and it is in fact cleaning up two older, normally aspirated cars I have with oiling and ring issues, installed in one Lexus and one older Acura (Isuzu).

Oil burning around 150k, although switching to Valvoline Restore & Protect I've basically eliminated it. Seems to be related to carbon buildup in the low tension rings.

Just another clean option to compete with Valvoline.

Mannol is a legit brand. Although not as critically acclaimed like Liquimoly, Rowe, Fuchs, Addinol, or Ravenol. Probably on par with Voltronic.

Pouring it in it seemed thinner than the rating would suggest. When I turned on my engine (NC MX-5) I noticed a new ticking noise that doesn't go away.

Turns out it's the hydraulic lifters.
