Diabolical!

Good news for me. Thanks for doing the legwork. I've been running Mobil 1 in every vehicle I've ever owned and have always been satisfied. I even run Mobil 1 in my Prius, lol.

Argonaut, are you using the 5w30 just for the track, or all the time?

Wow! An informed opinion. You hardly ever see that anymore. Thanks, man! I'll be doing a full synth switch on my next oil change.

Great to know and thanks for getting the tests done and should quite some of the nay sayers about tried and true Mobil 1 and I have been using since the first change!

Hey Argonaut, please excuse me for going off topic, but I noticed that you changed from 4:10 gears to 3:73's? How do you like the 3:73's as compared to the 4:10's and why the change?

I would also like to hear from someone who has gone from 4:10 to 3:73. Please chime in. The reason I ask is with 4:10's, first gear is pretty much useless on the street. I'm beginning to wonder if 3:73's are a better street gear.

Be careful. I hear there's a lot of 3:73 on the street and it's pretty powerful. It's a gateway gear though. Soon you're doing 4:10, 4:30 whatever you can get your hands on.

Every time I think I've decided to go ahead and get the 4:10s I read something like this and then the doubt creeps back in.

I changed from 4:10 to 3:73 specifically for road racing. The 4:10s are simply too short on a race track, I was consistently running out of gear before I ran out of straight away. For street only driving...its a toss up. I loved the way 4:10s hit so hard but 1st gear was so short it was kind of a pain. IMO, for a toy street car 4:10s are the way to go. For a DD I'd personally rather have the 3:73s.
