Season is starting and have some Q's about oil Engine What brand do you use? Why? What weight? Why? How often do you change it? Why? Tranny What kind of oil? Why? What weight? Why? THANKS,
Currently I'm using 0W20 Mobil 1 synthetic in my enduro car. VERY, VERY watery. (Not thick) I haven't had any problems with it, and I ran it all last year. That means four or five 300 lap enduros. I only am running it because my little brother got it for me for christmas, and I didn't want to hurt his feelings by not using it, so I put it in. Usually I use castrol 5W40 Syntec full synthetic. I find their oils to be durable yet inexpensive. I like 5W40 becuase I don't want thick oil when I start my engine, as it's a twin cam motor. But I don't want thin stuff when it heats up and I am running 7000rpm for many hours. So 5W40 is a great oil for me. I change oil when I can see the oil gets dirty, and whenever I run an enduro at the milwaukee mile, as its so hard on the motor. If money wasn't a problem, I'd run Redline 5W50 high performance oil, but I can't afford it. I will NEVER use royal purple, as it is proven to disintegrate, causing motors to fail. My grandpa ran it in his old dodge aries enduro car and had an engine failure twice, and switched to castrol and never had a problem again. For trans fluid, I just use advance auto brand dextron trans fluid. Never had any tranny problems. It's cheap, and it works. 'nuff said
i use valvoline 10w/30 high sinthetic and change the oil every three races and add a bottle of engine restore at every oil chang its exspensive but it keeps the seals good and clean motor clean
ive been using valvoline fully sythetic 5w-30 with a quart of duralube when i change it (which is only when its starting to look crappy on the dipstick). I just wanted to say that last year the car i raced (everyone will like this part ) was a ford probe with the 3.0L and the last enduro race of the year i ran a majority of the second hour with the temp guage pegged on red, then the radiator exploded with only a few laps left so i ran it til the end. the next day i fired the car up and it runs and sounds just as good as it did before the race. my point being that i think it was the fully sythetic oil or the duralube that saved the engine. I have read some really interesting stuff about duralube and would 100% suggest running it
