Engine oil Castrol or Motorex

I always ran castrol gold motorcycle 20w50 on my Harley's.

I always go for Castrol Edge. Always have, always will

On my ( 2006 Mazda 3s 2.3l auto sedan 350k miles ) I don't burn a single drop of oil and the car runs great even the transmission and I've been sticking to 5W20 Castrol edge extended performance all year

My car is at \~7600 miles. I changed the oil at 500, 5000 and then I'll change it again at 10,000. I used Castrol Edge 5w30 for the first two and I'll use it for the third oil change as well. I'm going to send a sample of the oil at the 10k change to Blackstone Labs to see how the Castrol is doing.

I would recommend the Castro Edge PROFESSIONAL 0w-20. Been using it in my wife’s LR4 since we got it and it was the consensus on best oil when I first did my research. It’s a little pricey but we’ve had zero engine issues with this.

we run castrol edge in our ‘04 FXT.

My rotary expert in north Texas recommended that I use 10-30 conventional oil. I personally prefer Castrol GTX

I use Castrol Synthetic 10w-30 on mine.

It’s thicker oil, so I feel like it gives the engine better protection. With 272k miles on it, I figured why not.

Currently using Castrol Edge 5w-40 fully synthetic, previously was using Estremo Heatpro 5w-40 FS, differences is so minimal to the point where you just neglect and forget about it....

Smoothness the same, silky smooth.

Car feels slightly like just slightly lighter on pickup with Castrol.

Yes, Castrol is crapola, so is Kendall. Valvoline is the best.
