No, but I did keep 2 quarts of oil and a gallon jug of water. My Mazda Protege was notorious for burning oil and overheating

Pros: kept oil and water

Cons: burning oil, overheating

Vehicle: Mazda Protege

Change the oil at a minimum, and do it regularly. Use a quality synthetic high mileage oil and change it again in a couple thousand miles, then change on regular 5k mile intervals.

Pros: quality synthetic oil

Vehicle: Mazda 6

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

Pros: runs like a gem

Mileage: 202000 km

I have run 0w20 in my 2013 Mazda 3 skyactiv for 244,000 miles. It doesn't burn or leak any oil between changes. I change the oil and filters every 5-6,000 miles.

Pros: no burning or leaking

Vehicle: Mazda 3

Mileage: 244000 km

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.

Pros: cheap, easy to get

Cons: no frills

I personally am changing my own oil with full synthetic on my 23 2.5T every 6000 km or so. No need other than peace of mind for me. Doing it myself only takes 30 minutes and $35 in oil, filter and crush washer.

Pros: peace of mind

Vehicle: Mazda 3

Mileage: 6000 km

Lucas OS works great. It's some amazing stuff, BUT. Do not go over your oil change intervals. Once the Lucas additive starts breaking down it turns to a nasty varnish. Went 7k using synthetic amsoil z-rod and Lucas OS, on a new rebuilt 4.0l. Lost a lifter and ate up the cam lobe.

Pros: amazing stuff

Cons: turns to nasty varnish

Mileage: 7000 km

they only say you can do that with their Mazda-branded oil. That stuff tends to be expensive.

Cons: tends to be expensive
