Engine oil Castrol or OEM Toyota

I run Castrol (bought at Walmart), like my father and his father did before me...

Stick to the 0w20 and 10,000 changes. My car has over 235,000 and uses zero oil between changes.

5k or 6 months just like a new one. use the recomended toyota/lexus brand oil.

I've been using the 0w-20 (what my Sienna calls for) for at least a decade, and it's perfectly fine.

I use it in my non deleted CJAA (dumb) but I haven't had any issues (yet) and it doesn't burn oil.

Have a 2016 Corolla ZR. Have only done oil changes, bought the car at 49Kms its now 105ks. Only thing ive ever need doing is oil.

2014 VW Passat 1.8TSI engine. 249k miles. Did the recommended oil change at every 10k until 125, then every 5 k. Transmission fluid change every 80k, looking back, will switch to 60k, just to be safe.

I've been using Castrol GTX High Mileage for almost 10 years in my 2009. I've always done 10,000 mile changes and I've got 298,000 miles on it. Blackstone tests on my 10,000 mile oil say it should be good for another 2000 miles.

If you are using ToyotaCare, they will push 10k/1yr oil change interval. If you willing to pay for every oil change, they don't care.

One time I had the oil bug bite (keera) and I decided to get the best oil. Castrol (I don't remember the number) but it was 340 AED for a gallon. I poured it into the engine and it felt good. That weekend took it for a desert drive and during one of the breaks, the entire oil just leaked out of the main seal. The oil was so good that the engine didn't have the tolerances to hold it back.
