what are locations you can buy Amsoil or Royal Purple stuff ? Do they sell these items over the counter ?

Royal purple can be bought over the counter and amsoil cam ge gotten online.

And the spun bearing has nothing to do with the weight of the oil. At my quick lube we use 10w-30 on 95% of all cars new and old.

For Amsoil, just go to amsoil.com and locate a vendor. A lot of the time there will be either a local supplier or even someone that owns a shop that can get it for you. You'll be looking @ probably close to $50 +/- w/filter & Shipping, but the oil will last twice as long as Mobil1 and the filter lasts 5x's longer....

You can get Royal Purple OTC at Pep Boys I think, but no one has their new filters. As far as I know they still don't have any on the market and don't even sell them on their own website. The old filters are only equal to Mobil1/Motorcraft filters so IMHO if you're looking @ RP, you may as well save your money and just find a Mobil1 sale.

sounds good man, I was just pricing it on Orielly's site and they are selling RP for about 9$ 1/qt so we will see, didnt see there filters like you mentioned being available... but did see that K&N is selling filters too, didnt know they made them for oil filters too and go for about $13

We do have a amsoil rep around here somewhere, but just have to look for them. Used to see them setup at some events.

Well its the only thing we couldve thought for that to happen. Cause its the only thing he did wrong in the maintenance is run heavier weight oil.

I just cant see that happening to a 30+k mile motor.

I get my Royal Purple Online, saves me money than going locally.
Same with my K&N Oil Filter and Air Filter. Just bought those for my MotorCycle and an Oil Filter for my car, soon to be oil.

Our show using 10w-30 95% of the time as well, car, suv, vans, motorhomes ect...

The first number is the oil's weight, not weather rating. But yes, it determines if the oil is suitable for colder climates.

Which would be 5w for Winter and 10w for Summer. :D

lol, thanks mr picky pants.... :rolleyes: I think everyone gets the idea though.

I wouldn't use a K&N filter. Just a paper filter like all of the others out there except it costs more.. If you're going to use anything but and Amsoil filter you might as well just get a Mobil1 or Motorcraft.

I can't believe people are still changing their oil at 3k miles. Modern oils can go so much farther then that. The filter technology and oil technology is so far advanced from the 60's and 70's that 3k mile changes are a waste of your money. Regular non-synthetic is good for around 7k and synthetics can go 10k+, some have gone as far as 20k miles and more. I change mine every 7-9k sometimes more depending on how much nitrous and abuse I have done during that time.

As advanced as oil is nowadays, the number one cause for oil breakdown is still there: blowby. If combustion gases or fuel never hit your engine oil, you would have changing intervals similar to the trans or diff. However, the blowby is there, dissolving the oil and making it slightly acidic. That's why I will never go past 5k for any car I change the oil on, even my gf's Civic (which recommends 7-10k). You can have the best oil and the best filter but the oil is still being broken down just as quickly. Until cylinders are fully sealed and PCV valves become a past necessity, I'll stick to 5k oil changes. Even Ford recommends 5k for normal driving and 3k for abusive driving. I personally think they switched to higher intervals lately solely just to compete w/ the Japenese manufacturers whom recommend longer intervals.

I change mine every 3k cause Vortech tells me too. Plus $30 every few months or so isn't that bad.

And to Spike's posts. Amsoil is guaranteed up to 25k miles because they are the only readily available true 100% synthetic oil. Their oils contain no petroleum, 100% man-made. They're also the only manufacturer that I would trust the oil filter over 5k miles, Amsoil has the only non-paper filter and guaranteed up to 25k. RP supposedly has one, but I've never seen it for sale anywhere, even online.

Unless their oil has a pH above 7 to compensate for the acidity that forms later on, I could care less if the guarantee says 25k intervals. The fact remains that blowby is what prevents oil from having a longer service life. For filters, unless that capacity is larger, again, you will not gain longer intervals. For filters, material has less to do with life while overall surface area is the determinant of that. Lastly, synthetic oils have to come from some carbon rich source. Petroleum based synthetics are not inferior because they do not start completely from scratch. In fact, they are just as good and cheaper as less energy and steps are needed to turn it into the final product.

Not bashing you or Amsoil, just separating marketing from facts.

Amsoil is less expensive than RP, Redline, and in some cases Mobil as well..

I would personally never use an oil for longer than 7-8k miles no matter the "guarantee."

How much is it for 5qts of Amsoil? It's kinda hard to beat Walmarts 5qt jug of Mobil 1 or any other synthetic they carry for $23.

The only oil that I'm aware of that is petroleum based is Castrol synthetics. I'm pretty sure Redline isn't (have you ever smelt it?), not sure on RP, and Mobil 1 is not petroleum based. On that note, I'm not sure on Quaker State, Penzoil, Vavoline, or Motorcraft.

I've always run 5w20 in mine and I'm pretty sure a few others including Spike do too. I don't see why it's necessary to run something heavier. Then again my oil cap used to say 5w20 but the book called for 5w30.

No, you won't beat a price on their mid-level oil. Amsoil is 100% Synthetic, "25,000 mile" oil. The only thing you could really compare it to is the "extended performance" 15,000mi Mobil1 that sells for between $8-9/qt.

My 5 quarts of Amsoil was $44.60 shipped.
