how much does a case of RP go for? Theres only 1 RP distributor within an hour of me unfortunately

For me it's 110$ but I don't know if it's with or without tax.

12 containers would last me a few seasons, I can definately live with anything under $150. thanks man

Personally, I think all you guys with oil that costs more than really good watch are all nuts. I defy anyone to notice the diff. protection wise between all those fancy a$$ oils and diesel oil. In fact most of the oil today that doesn`t have a racing designation on it has NOTHING that these engines need.

Our valve trains have sliding parts in them, meaning metal sliding across metal with a presure of at least 50lbs and a max of 175lbs. This situation needs moly and zinc and a touch of sulfer. NONE of the modern oils have this in them any more because most modern engines have no sliding parts (all roller) and for emission purposes. I don`t care what kind of propaganda RP Amsoil or Mobil have going on, they can not protect our valve trains effectively, they cannot use the proper additives BY LAW (EPA).

I change my 10w40 Shell Rotella T diesel oil every 1000km (being a dino oil I need to). It never has any nasties in it and is protecting my valve train from galling at a whopping $1.67 per litre. A 20l bucket from Walmart will give me 4 oil changes. Add the Wix filters at $6.77 each and you can see the appeal.

Keep in mind I`m pushing 600hp out of a relitively stock longblock. For you 300hp guys you could go 3000km between changes, I`m anal about clean oil. Rotella T goes for about 7000km in the average big rig before a change.



Food for thought......

I went in to Ztune maybe three weeks ago now to get an oil change, they were out of 10w40 that I had at the time and wanted again. They said 20w50 would be fine. So that's what I'm using now. Haven't noticed much of a difference. Oil pressure seems a bit better at idle compared to 10w40. They just recommended that I let take it easy a bit longer than I did with the 10w40 before having any fun and boosting her.

The ass dyno did tell me that it felt faster after the oil change, though

dont do it , go amsoil .

3400lb racing weight and 127.72mph in the quarter at 1.2bar (1.5 feels at least 50hp more) works out to 510 WHP. At 1.5bar I`m at least 600hp at the crank. That`s being concervative too.

so does any partsource

[MikeyRHD]

royal purple contains zinc/phosphorus additives (even more in the xpr line), amsoil dominator appears to as well(not sure about the regular line)

Does amsoil dominator still contain detergents for street use? I was looking on amsoil's site but couldn't find an answer.

Yea I used RP10w40. Car just had an oil change when I bought it, and then I did one more over the season (only had the car since June) as it was taken off the road a few weeks ago. I didn't notice any difference from before the change but I had a slight miss from poor plugs and didn't push it too hard.

The only time I ever noticed a difference with oils was in my old work truck (a 97 Ranger I owned a few years ago). I wouldn't change the oil until the oil pressure dropped to L when I turned corners haha. Then an oil change would prove a difference in the butt dyno.
