What type oil do you use?

Alright, so I used to use Royal Purple Full Synthetic in my subaru, but this is another world really, so I'm trying to get opinions. Not really going to be building much into it, will keep it N/A and want to get decent mileage out of it.

I use Super Tech (WalMart) 10w30 full synthetic in the daily drivers and M1 15w50 in the turbo cars. I do hpde/track events and found that the 10w30 M1 thins out too much when hot. I stick to oem nissan oil filters.

yea, I was gonna get a oem filter, but parts was closed today and that was my trip into town for the week. Its a pain having to do 100 mile roundtrip's to get something ya need.

Dino right now but 2nd oil change will go to Synth.

For cooking I like a extra virgin olive oil or anything with a high concentration of good fats.

From the limited research I did on oil the only difference in synthetic oils and normal oils is the longevity. If the SAE rating and the viscosity are what your owners manual specifies then the synthetic is going to hold up longer under harsher condtions, which only helps you out if you don't change your oil at the specified intervals. So buying synthetic might be worth it for the added peace of mind, but I'm not so sure that the lubrication of your engine is helped either way.

Also synthetic is suppose to be alot better in cold climates I can't remember why so it's alos worth it if you live in a lot of snow.

Also synthetic is supposed to be a lot better in cold climates. I can't remember why, so it's also worth it if you live in a lot of snow.

That's the main reason for using it in colder climates. It's worth it.Where I live it gets REALLY cold, and synthetic oil does not thicken up like normal oil. On a cold start, you want that oil to start circulating through your engine as quickly as possible. Synthetic does that. Regular oil can get so thick (especially if you haven't switched to a lower viscosity), that it sometimes takes up to 30 seconds for the oil to find it's way to the top of the engine. No wonder some engines don't last long up here. Now some venting: What makes it even worse is the idiots I've seen that start their car in the middle of winter, and then rev the crap out of it right away, thinking this will actually help it warm up. The same guys also refuse to use a block heater, because their car starts no matter how cold it is (they are actually proud of this). These guys don't get the fact that it's not about whether it starts or not, but rather it's about saving your engine over the long haul. If the engine is warmed up a bit with a block heater, the oil will flow better and your engine will be happier. Hope this all helps.
