Engine oil Castrol or Shell

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.

Rotella 5w-40, for no other reason than it is good oil that I can use in every internal combustion engine I own, including wet clutches.

Rotella 15w40 for mine. Never an issue and good oil reports for several hundred thousand miles.

Rotella T6 has been good to me.

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.

Regardless, I haven't heard of Aral, but I wouldn't knock it without proof that's worse than Castrol.

Car has been at the stealership for three weeks. Same transmission TC seal leak. Bolts and seals also needed replacing. Car is 45 days old with 4K KM’s.
