Engine oil Mobil or Castrol

Mobil3000 5W-30 even boosted my oil pressure and helped with cooling.

140K '19 Tigi 2.0T, switched from Valvoline 5W20 Syn to Mobil 1 0W20 ESP (Dexos D). Changed oil due to oil consumption and secondary air injection DTC. The "latest" member of the Mobil 1 family touts lower emissions (less vapor in the PCV system).

Mobil1. Period. Years of personal experience. When I was in my 20's twenty years ago I was using Motul too because everyone else was and I didnt know any better. Try them out. Detergents, how clean the oil remains after each oil change and how smooth it runs were some deciding factors for me.

I use Castrol Edge. It's cheap and good. I drive a lot and I change oil every 3k miles so 5qt for $25 just fits my life better.

Under warranty Toyota Oil. Pag sa labas na Castrol or Mobil 1.

Anecdotally, Mobil 1 seems to burn off less than Pennzoil for me so that is what I use.

B46 which is essentially a B48 engine. 105000km. Running Castrol Euro Car 5W30 in the summer and 0W30 winter. Live in Canada so the ambient temp can range from -30C to +35C.

My 14' outback burned 1-2qts between oil changes based on driving (lots of short trips or visits to the mountains burned more.) Never had any blue smoke on startup or during driving.

Down to .5-1 qt low after 5000 miles now.

I'm at 308k miles and use cheap Castrol engine oil, house brand transmission fluid (the correct kind though), and the cheapest coolant I can find.

Castrol sucks
