Engine oil Castrol or Lucas

Personally I buy exactly the factory oil, from a manafacturer that factory put in, in German cars it's Castrol, French are Total and Elf, Italians use Petronas Selenia.

My Miata has almost 300k on the original head gasket I started using the far right a few times ago and I don’t leak a lick of oil

My r53 loves Castrol 5w40 and Mann/Mahle filters.

Castrol Edge, I have used it forever in both my vehicles and I 10/10 reccomend it.

I used Castrol magnatec 5w30 Fully synthetic every 6-7k Miles.

I used Castrol edge 5w40 euro car when I had my car.

I’m not going to argue with anyone about what it does but I’ve used Lucas for a long long time I have a 93 Chevy truck with 400k miles that I have never taken care of correctly I have run it out of oil overheated it overloaded it and abused and mistreated the engine in that truck and its still able to do any thing I need it to.

I run Castrol Edge in my VDub. It's the European blend that is approved by VW as shown on the back of the jug.

I use this on my 2003 Passat 1.8T probably every 2-3 oil changes. Motor has 269,000 miles and burns a smidgen of oil on startup. The Lucas seems to help a bit.

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.
