Amsoil's my brew of choice. It's in my rear and it makes no noise. Just waiting now for my oil change to come up so i can put my amsoil in the engine.

i believe given my choice i'd run amsoil, but it's hard for me to find and i don't do the on line ordering thing, so i usually run mobil 1 synthetic and pennzoil for dino oil.

amsoil everything from bumper to bumper, better motor oil, better coolant that works better than royal purple or redline additives, trans fluid and gear lube in the rear. and amsoil filters.

I'm an Amsoil dealer (just to get the discounts) and it's decent stuff. Amosoil says it's better than Mobil 1, but who the heck really knows? Both of them are far better than you will ever need them to be.
I like running extended oil change intervals on my daily beaters. Good quality synthetic stuff lets that happen without trashing the motor. Back before I went synthetic I was changing oil every 3000 miles (like a good little consumer sheep). I was changing oil on SOMTHING every weekend! Since going to Amsoil I bump that up to about 10,000 (they say I can go longer but I'm the nervous type). I've got about 70,000 miles on 3 vehicles, both new and really old, doing this routine with no problems to report at all.

I've been using Mobil 1, but I'll be most likely switching to Amsoil, since my car sits a lot.
Thanks

And DAMON...can i buy some amsoil from you since you're a dealer and all. My oil change is about due.

I've got a '96 with 4,100 miles on it, so it sits a lot. With Mobil 1 15W50, I have no leakage issues. Ditto on the '86 with 47,000 miles, and all the other vehicles with various mileage that sit for extended periods. I don't believe that leakage can be blamed on the lubricant. Even kerosene, JP4, and all its derivatives can be kept in a container that is properly sealed, and that stuff will wick through almost anything.

I like royal purple, I put that in a friend of mine's car it was a dodge stealth v6 dohc non turbo and you felt the difference cuz we put it in the engine and transmission, less friction, more power, nice stuff the engine reved up smoother and the idle was good, so either the oil is awesome or his engine sucked

In addition, changing to synthetic along the entire driveline yielded an overall net increase of over 16 HP at the rear wheels. There's no sdoubt the less friction = more power. There is also no doubt among those of us who have been deep into a synthetic engine after extended mileage that the decreased friction is apparent on the micrometers and telescope gauges. I'm a believer.
I also feel that Amsoil has been at the forefront in synthetic lubrication for vehicles, but Mobil has made some recent improvements that nearly erase any difference in performancec of the synthetics. It's sad for Amsoil that their distribution system is not better, since their sales could be significant with proper advertisement and distribution. Maybe some day.

some seals will leak slightly
after going to some of the thinner Syns (like 5-30 M1).
I think the mag tests used Royal Purple and got ~10hp.
I think SLP uses Redline.

We use Redline in our Spitfire, though we use valvoline mineral oil on break in. Redline significantly reduces oil temp at road racing speed and gives marginally more power. It's 8 bucks a quart and I would definately not use it on a streetcar. Redline has always given us asesome protection under race conditions.
On a streetcar that you plan to keep for awhile, I recommend Valvoline's Durablend, it's a mix of synthetic and petroleum oil. It's a good balance of better protection and good cost.
On a side note, we just started using Redline shock resistant gear lube in the Spitfire's trans and rearend. It also gives more rear wheel power and better protection.
I didn't read any of the previous posts cause there are too many, so if I repeated anyone, my bad.

Okay, I'll chime in.
None of the synthetic companies hesitate comparing their product's performance against petroleum lubes. AMSOIL is willing to publish test results comparing their products to the other guys' synthetics.
That tell you anything?

redline or amsoil would be my picks
have heard nothing but good about them
only thing I don't like is I can't find them local and they cost money
well lots of money

From what I understand, synthetic does not create leaks. It just finds leaks that were already there.
Mineral oil forms deposits and what-not that might fill in these leaks, plugging them up. However synthetics do a very good job at cleaning your engine out, thus removing the plugs, and making it seem like the synthetic oil caused your engine to leak.

I think I experienced that. But to just not leak I would have rather stayed with regular oil.

Re: Mobil 1 ,Royal Purple ,Redline ,Amsoil ????
Amsoil makes a good detergent that you run your older engine with right before you change your oil. I did this on our farm truck before switching to AM10-40. There was literally ***** of gunk that was coming out with the pennsoil that was draining out of the motor. This was a 87 2x4 22r powered yota with 220k on the clock. It probably gets driven around an hour or two a day on the farm so dependability is key. Afterwards the truck didn't smoke anymore right after startup. Still no oil leaks and burns no oil. The heads have never been off this motor either. Now it has around 300k on it and keeps on ticking.

Re: Mobil 1 ,Royal Purple ,Redline ,Amsoil ????
I have used Amsoil, Mobil 1, Redline, Royal Purple, and am now using Shell Rotella T Full Synthetic 5-40w. I believe is still has zinc in it which a lot of oils have removed from the formulation for emmissions...but some Diesel Oils still have it.
Haven't seen the Amsoil high temp sheer comparsion between these two oils.

I have used Mobil 1 on the rear axle, transmission, engine and used Mobil 1 grease for my Camaro since 1993 when I got it. Never had a problem with it. Btw, the car had 64,000 miles when I got it. Now 120000 miles+.
