Rating 4.5

Since then, I've changed my oil to a low SAPS VW 504 Mobil 1 5w30 ESP X3 which according to lubrizol has superior resistance to deposit and sludge formation. At this point, I've got consumption down to around 1qt/1400 mi which is a great improvement from where it was before. Hoping for further improvements with time but pleased with progress.

Pros: superior resistance to deposit, sludge formation, improved oil consumption

I’m slowly switching to Mobil1 since I started doing oil analysis.

It has no sodium and therefore a good way to see if there is a coolant leak.

Pros: good for coolant leak detection

Castrol in my daily driver. The daily would have a slight ticking when warming up with other brands, not with Castrol, so I been using it for over 100k with no issues.

Pros: no ticking when warming
Cons: slight ticking with others
Mileage: 100000 km

Castrol Engine oil

Have a look on Amazon they do some good deals on oil, I normally stick it in my basket and wait for it to drop.

My old car was Castrol 5w30 Magnatec, £28.50 for 4l on Amazon £43.99 from euro.

Pros: good deals on oil

I've used Mobil 1 in my 2011 Mazda Speed3 for 8 years. My 2019 Bullitt gets Mobil 1 as well. Mobil 1 is reasonably priced and meets the spec required by both cars.

Pros: reasonably priced, meets spec
Vehicle: Mazda

Funny, I changed my oil today for the first time as well. Also 1700 miles. Not black but certainly a lot darker than the Mobil One 0w40 that replaced it..

Pros: darker than Mobil One
Cons: oil darker
Mileage: 1700 km

I tried Mobil 1 15w-50 for about 15 minutes (literally!) in my 2.0 one time. The valve noise at startup was so bad I drained it immediately.

Cons: valve noise at startup
