Reviews of Castrol engine oil

Castrol Power 1 ultimate is great and cheaper too.

but real talk: Castrol GTX Synthetic 10w40 in Tennessee summers and 5w40 in winter.

5W30 Castrol edge full synthetic

Castrol Syntec 5W-30, because of this: [https://my350z.com/forum/engine-and-drivetrain/258663-vq-oil-analysis-and-info.html](https://my350z.com/forum/engine-and-drivetrain/258663-vq-oil-analysis-and-info.html)

Between it and the Castrol Syntec 0W-30 it has less wear indicators in the oil than any other brand, at any other weight.

Redline and motul are the best but I’ve been running catrol for 50k+.

As far as the castrol goes I bought a used 2018 Kia soul that had a slight knock in the engine for ultra cheap and I was able to make that sound go completely away once I switched to Castrol edge. My vehicle also seamed to burn a lot less oil.

Jeez I feel like an outcast. I run Castrol 20-50 lol but the car loves it

I might switch to liquimoly like a lot of ppl do but I’ve always stuck with the Castrol edge 5w-40, changing around 5k

I been using castrol 5w40 since I got the car new at 82 miles no issues. Sent my oil samples to blackstone for analysis and oil is really good even at 10k.

I've tried most of them. I went like 2 years doing all sorts of testing on my car and never noticed a difference. I stick with good old Castrol Edge like the factory recommends.
