If it’s a 5w30 it’s a 5w30, that’s why we use that norm, to tell how the oil react in hot/cold states. (And then we have more norms to determen what quality of oil we need)
The synthetic part is aditives that enhance the oil, not just making it thiner, donno why you would think that?
Damn I didn’t know that, but It’s because of the engine design (seals) If you rebuild it with new seal, i would deffently go with synthetic from there!
We don’t really have any rotory engines here in Denmark, so never worked on one.
The Oil data, was from Elf that supply our oil
http://www.racingbeat.com/mazda/performance/rotary-tech-tips/synthetic-oils.htmlWe're not talking about weight. You clearly dont know enough to understand. Convential oil is a thicker oil. Do a oil change after 500 miles with both. You'll see the synethic flows more freely. The regular oil will run thicker. Not as smooth. Guess what? When you're at high mileage with a leak ass gasket or something in your truck, you're not gonna want your synethic oil to be so fluid. You're gonna lose it a light faster. It's not a hard concept to understand. Stop thinking you know everything because you can read Google.
