Engine oil AMSOIL or Lucas

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 like amsoil 5w-30 and do a liquimoly engine flush with every oil change.

On a new car, I change at 750, then again at 3000, and after that I do my regular once per year or 25,000 miles, whichever comes first, as stated on Amsoil Signature. I've been using this oil for decades in cars, trucks, and tractors. It's incredibly good oil.

I do 3k with Amsoil SS as well. Blackstone analyses of TBN show I could easily do 5,000k.

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.

5000 miles with a quality full synthetic will serve you well for the life of your vehicle.

Maintenance, that’s what I’m focusing on rn so far ive done oil and coolant, went with amsoil and Nissan blue

I used AMSOIL signature, and do yearly oil changes.

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.

Absolutely Liqumoly!

Please never put Amsoil in a Volkswagen they under rate their viscosity/ wt ratings and the only time I used their oil I ended up spinning a rod bearing in my first R32
