Engine oil Castrol or IDEMITSU

I change every 10,000 km - 7000 mi.

Castrol or Mobil full synthetic.

To me that is much better than running any brand of oil longer.

I’m a Castrol 0W40 guy myself.

It doesn't seem like I burn any oil in my Rabbit. 0w-20 seems too light to me, also, I'm running Castrol Edge 10w-40.

I run Castrol GTX 10w40 in my FD. Premix TCW2 2stroke oil .5oz/gal.

Engine seems happy as can be.

I use mobil1 or castrol full synth 0W-20 for prius engines below 200k and 0W-30 for those above it. More than 30k mi now so far so good. I like the castrol better bec my engines sounds much quieter vs m1.

I use castrol magnatec beucase it has some kindof ionization tech where it sticks to metal surfaces to reduce start up wear which the prius is constanly starting/stopping.

As someone who lives in Florida, and has a high mileage m54 motor, I only use Castrol 5w40 and 5w30 if I cant find the first option. Runs amazing and daily driven with some abuse lol

Go to wallmart and buy two jugs of Castrol Edge Full Synthetic 5W-30 and then just purchase a couple filters off of FCP Euro.

The 2020 has been great but the engine still clacked and groan albeit nowhere near the 19. With the 0.5 quart of Castrol 5W50 I love the car now! Pickup is great and the engine being pettier seems to help the transmission shift better also.

If you want to do 5k oil changes, best to switch back to Castrol GTX or any cheapo oil as you'll have no significant advantage using synthetic for short periods of time.
