Engine oil Castrol or OEM Toyota

I have a 2010 civic si, I use shell rotella T-6 5w-40 due to burning issues and one quart of Castrol 5w-30 high mileage full synthetic (I’m picky lol- but my car runs smooth and has consistent oil levels on the dipstick through the weeks after oil change)

Buy Castrol Edge engine oil for your Mazda 2.5, but do get the Mazda transmission oil.

I bought a 2008 toyota yaris for $5.5k on fb marketplace. Had a prepurchase inspection.\n\nI love that car for the exact reasons you mentioned. It\u2019s been with me everywhere ive gone, is super cheap on gas, and just requires oil changes every 8000 km.

I\u2019ve always preferred Castrol gold.

In my 323i with the 2.5L N52 engine, I use Castrol Edge 5w40 with the appropriate LL specification. Oil consumption is 3000 km per liter, with 190,000 km on the clock.

Castrol is really good considering cost and quality.

I replaced the plugs, oil/filter and air filter with oem parts when I got it. I\u2019ve been changing the oil at 5k intervals with the recommended Castrol 0w-20.

Always have done 10k on my ‘22 RAV4 hybrid, which equates to every five or six months (did the same on my ‘16 RAV4 hybrid as well), and do the same on my ‘12 Prius C I’ve had for 11 years now. No issues.

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

I tried Castrol and was not a fan, found it burned faster than any oil I used.
