Engine oil VALVOLINE or AMSOIL

My 2016 GT350R has almost 25K miles and has never needed oil between changes. I use Amsoil every 5000 miles, sooner depending on track abuse.

I have been using various Valvoline synthetic oils 10+ years in multiple stationary engines, tractors, diesel and petrol engines. No sludge, no varnish inside the engines, and never worn an engine out.

Amsoil 100%, I tested it quite a few, and I’m noticed the least amount of decoration and power loss with it

I use Valvoline restore and protect. It fixed the tick after a few oil changes

5W30 Valvoline Restore and Protect is good

5w30 Amsoil, ignore the tick it's normal.

Also, I have upgraded to Amsoil Synthetic Engine Oil which further helps for maintaining DPF health as it reduces ash that can accumulate and plug the filter.

Nissans are hard to read too. Valvoline always shows me the stick and I can barely see the proper fill level. Car is usually fine.

Jednom sam prije vi\u0161e od 10 godina u jednom trgova\u010dkom centru kupio ulje za auto, gradacije koja je trebala za ono sme\u0107e od VW -ovog 1.4 8v benzinca... Valvoline, barem je trebalo bit po deklaraciji... i kolega mi to zamjenio, naravno i novi filter... kad nakon tjedan dana po\u010deli lupat podiza\u010di ventila...
