Engine oil Eneos or Lucas

Been using Eneos & changing it every 4k miles/4 months. Congrats on the WRX

There is no “break-in oil” just ENEOS brand 0W-20. KIA and ENEOS have a partnership and the factory oil fill is this oil

Right now I have some Lucas High Performance, but the brand is relatively immaterial to me. As long as it's a reputable brand and it meets the spec in the manual.

I'd stick with oem or put some better stuff like Motul or Eneos into it. Eneos has some relation to Honda oem oil I forget the story. I use to put only mutul into my car but have recently switched to Eneos, will be putting eneos 0w-20 race prior to tune.

For shits and giggles I switched to ENEOS 5w30 synthetic in my 2 current vehicles and now I'm able to go 5,000 miles between oil changes and while some oil is still consumed, it stays above the "add" line on the dipstick without adding oil between oil changes.

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

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 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.

Used it for years in high mileage motors. 215,000 on a 1.8 turbo VW

used no oil between 5,000 mile changes.

I’ve used Shaffer’s and now ENEOS and T6 when it was the in thing and I can’t really tell a huge difference.
