So, where might one find Amsoil, Redline oils - diesel or otherwise? And, is there a reason folks here seem to be going with heavier oils when using synthetics, or diesel oil, than when running "normal" petroleum oils?

Diesel engine oil is available at Walmart and most auto part stores. Standard dino diesel oil weight is 15W-40 - a smig thicker than 10W-40 when cold but close enough since most of us don't ride when it's freezing. No reason to use anything heavier unless riding in the heat of summer where some people like to go to 20W-50. Amsoil and Redline oils are harder to find - try Google.
 
Every owner will have their own opinion.
I've read the studies, and concluded that motorcycle-specific oil is a waste of money.
In one study, motorcycle-specific oil was compared to Castrol GTX 10W40 with about the same results, and the leftover money jingling in your pockets.
All 10W40 oils are not fuel conserving (or whatever they call it) which is what you want.
Pep Boys now has 5 qts. of the GTX with a Valvoline filter (maybe you can use the filter for your car) for $12.99. I bought mine yesterday.

I'd generally agree but motor oils have changed in the last few years so unless the test was done recently (as in the last year) it's not really valid anymore.

The problem with auto oils is they have to be formulated to not contaminate the catalyst(s) in modern cars. The tightened standards required the oil manufacturers to reduce the amount of zinc and other high pressure additives in the oil recently. Even diesel engine oil is effected these days, but to a lesser degree. For that reason, I used to be a fan of auto oils but not any more.
 
Redline

Redline is available from Summit or order direct at redlineoil.com
 
ugh. this thread topic again???? i just switched from pennzoil dino 10 40 to rotella synth 5 40, it seems delicious. only, like, 16 bucks for a gallon of it from auto ripoff zone, cheaper than dino these days. many will say it matters not, so long as it is not energy conserving (naughty for wet clutch) and you change it regularly.
 
Does anyone use these any more?

Does anyone use these any more?

Every shop (5) I ever worked in had an oil refractometer, and a brake fluid refractometer.
And every shop I ever worked in had it buried in the back of a drawer, disused.
Does any one use one anymore to evaluate their own oil (or their claims?)

Just curious.

Oh, and if you don't know what one is, here's a link:

Where to get AMsoil?

Where to get AMsoil?

In Canada, Canadian tire carries it in litres.

I can vouch for the Red Line oils, a friend uses it (and Royal Purple) in his 800+hp stock cars and goes the entire season without refreshing the engines. Dyno pulls show it adding a few ponies, too.
Plus, it is impervious to alcohol, which he runs one engine on. Since you must run so much fuel through the engine to make the same power you wash down the rings with alky and it gets into the oil tank (dry sump).
Drain the oil, flash off the alky and pour the oil right back in!
He also uses their gear lube, this stuff won't wipe off! Pull the gears out of the rear end, hang them in the trailer and weeks later they are still hard to hold onto. He also goes the season without changing it. used to use Valvoline synthetic and after three weeks it smelled burnt.
So, now I use it in the trannies and rear ends of my Guzzis and it will go in the GS.

Many speed shops carry it or go to the dealer locator on their website.
 
I just use Delo 400 15w-40 and have for long time. 80K+ and rollling great. Rotella 15w-40 works great too.
 
Both Red Line and Amsoil are available locally in the Mpls. St. Paul area. I am going to try Amsoil 20w 50 since there is a guy that sells it just down the road from me.
