Owner reviews for engine oil

3.0 n52 when I got the car it had 5w-30 and the oil was leaking slightly. Changed 5w-40 and the leak stopped all together. Engine is smooth as butter

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.

I have a Svartpilen 401 2024 model. I did a 500 km ride recently, I didn't notice any drop in the oil level. In India, the engine oil used for these bikes is Motul 7100 10w50 Fully Synthetic.

I am using 15W40 Shell Oil for the last 8 years. No issues. 160k Kms on the Odometer

Used wolf for 10 years, no problems yet.

Castrol is really good considering cost and quality.

Personally I do 10k miles with Mobil 1 high mileage and a Walmart Supertech filter on all my vehicles and they're all well over 300k miles with no oil-related issues.

I would choose Mobil 1 Extended Performance if you're going with Mobil 1. It has the best addative package of the bunch. It's what I run because a 5Qt jug is $28 or less at Walmart.

Never had any luck doing an oil change every 10K miles on any cars in my fleet. However, with a new car that’s hybrid that I bought last year, I’m praying that I can push the oil change interval every 10K

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...
