Engine oil Castrol or Lucas

Always used Castrol in my cars when I\u2019ve had the choice and never had a problem.

On my previous car, a VW Golf 7 2.0 TDI I used to change the oil (Castrol 5W30 Long Life) every 12000km.

Had an 02 explorer with the 4.0 that had 286,000 and still running like a champ when I sold it. It was on its second transmission and everything in the vehicle was falling apart but that motor never once had an issue. Regular maintenance and oil changes every 10 to 15k using Castrol GTX fully synthetic

I have a 2012 gmc terrain 2.4l currently at 202k. I’ve used Lucas oil and restore and protect Valvoline oil the last 50k. Still runs like a gem with 177-182-179-175 compression cylinders 1-4. Used to be 155-149-144-168 before I started using both these oils

I put some Castrol 0w20, no issues.

Castrol mangnetec gave me good performance but in city conditions it gave inconsistent fuel economies for me and under normal cruising speed 80-90 it performed really good. But for me it felt like reaching higher speeds above 100 felt slower compared to shell. Initial pick up of my car felt higher with this oil.

I exclusively have used Lucas oil for my sportster motor for 5 years. The bottle looks cool, that's it. Full synthetic oil, no frills, cheap, and easy to get.

I have a 2012 civic with 220k miles still use Castrol 0w-20. I've been using it since 500 miles switched to the high mileage stuff around 100k

My mechanic added a bunch of Lucas to the oil, which he said might at least quiet it down, and it did. It's quieter now, but I can still hear it at idle.

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.
