10w30 should be good in Hawaii year round
What kind of motor oil do you put in your car?
- Thread starter PICK3
- Start date
a couple mechanics i know say the majority of motors that run some types of synthetic oils wear out (the rings) prematurely compared to motors running regular oil
i would never use synthetic regardless

that's why I ran fossil oil for the first 5000 miles and then blendedDevastation said:
apparently you want the regular oil at first to "seal" or some shit the rings

tidbits from
Notice how each time we change the oil, there is still an initial spike of wear metals, but the spike is smaller at each phase. We are working on a hypothesis: that the true break-in of an engine is at least 20,000 miles, and that, perhaps, during the first year of an engine's use it would be wise to change more frequently, and only start moving toward extended oil changes once the engine is older. It'll be interesting to see what comes up in the Mobil 1 re-test phase.
Past Results
To date we have completed our tests of Mobil 1 and Amsoil. Mobil 1 held on for 18,000 miles, and didn't need its first oil filter until 12,000 miles. For all the details, visit our Mobil 1 Test Results page. Amsoil was time-limited to 14,000 miles (its year ran out), but it made it the whole way without a replacement filter. It's not a total success story, though, as it had some trouble with its viscosity. To read all about it, visit our Amsoil Test Results page.
hree months or 3,000 miles
Well, it seems to work. But for most engines it's a lot like changing your bath water partway through your bath. More than likely you're wasting a lot of time, money, and oil, but you're certainly not likely to be harming the engine any. A 5,000-mile interval is gaining popularity and is probably more realistic, but it's still a guess.
Based on our actual raw interval of 18,000 miles and our corrected interval of slightly over 10,000 miles, we can safely say that theories one (change every 3,000 miles), three (follow the dash indicator), and four (the Paradise Garage method -- sigh) are rubbish and worthless.

I've done major work on plenty of motors and have found valvetrains pretty clean when run with Castrol GTX and Mobil 1...those that used Pennzoil or Valvoline had a caramel color...
I personally live and die with Castrol GTX.
