Oil change frequency w/ Royal Purple oil?

[47SLTDuRide]

I heard all the rave about Royal Purple engine oil so a few months back I bought a few quarts and thought I'd give it a try albeit it was the most expensive engine at Pep Boys. So far I put in over 4K miles since the oil change. I was once told by a mechanic that I can run 6K miles on full synthetic oil. Can I put in anouther 2K miles before my next oil change? Before using synthetic I'd just buy the cheap Proline oil/filter and have an oil change every 3K miles.

Also, my family and I will be traveling from SoCal to the Bay Area for Christmas, what's the best tire pressure for cross-state traveling? :drive:

Any help and advice will be appreciated. Thanks and Merry Christmas! :mullet:

heard people put over 10,000 miles on syn oil. but they all get their oil analized to have it checked out. but 6,000 I really sont see a prob. goto this site and ask the question over there they know it all when it comes to oil.

bob is the oil guy (http://theoildrop.server101.com/ubb/ultimatebb.php)

this would be your best bet

as far as tire pressure what ever is on your door plate. under and over inflation is bad on a tire and can be dangerous. so if its 35PSI then go with 35 PSI

I try not to take risks with mine, I use Mobil one and Royal purpel, I Alternate than at 3000 mile intervils.....But i just put in that new Mobil one clean 7500 mile stuff, ill take it to 5000 miles before oil change

royal purple ever 5k, i dont doubt i can last longer, but ive seen some ppl who have ruined there cars because they did, granted they wernt using synthetic, still scared me though.

if you change the syn oil every 3K miles. your justwasting money. and should just use dino oil. 5K would be the time I would change syn oils. I am about ready to try some german castrol Syntec 0w-30 suppose to be some really good oil. as it not made in the USA but imported from germany.

Oil change should be about due by the time I get back from the Christmas travel. Thanks again guys! Merry Christmas! :mullet:

I do 6000 miles per oil change, but change out the filter every 3k... And I am religious to Royal Purple and a K&N oil filter... Be sure to replace what oil you lost in the filter change...

wait, how do u change a filter without taking all the oil out first? or do u take all the oil out then put it back in? little confused

[addicted2blue00]

lately ive been just using syn, valvoline 5w-30 75K mile syn and k&n filter, and change every 5-6K, been thinkin of gettin an oil magnet.

Ace you can take your filter off and only loose under a QT of oil. whats in the filter and whats left in the line to the filter. it wont drain all your oil. as your filter is higher than your oil pan.

[scentralpirate]

I typically change it out after about 2 or 3 filter replacements .... so anywhere around 6 - 9 thousand. (it stays in longer during the winter when I don't have a garage :cussing: )

damn....i'm traveling in my dak from So Cal to bay area also :biggthump
my sister lives in Hercules. Havn't seen her new place since she lived in Concord.
changed my oil less than 600miles ago :biggthump

[UsRanger11B1V]

I would just stick to Mobile one syn. oil. Question, what is the difference in the 5000,7500, and the 10,000 mile oil,beside price?

Get out of here! We're driving directly to Hercules from LA,too! My wife and I have relatives there. What a small world. You driving your Dak up there? Hey, if you see a white lowered Durango with 17" R/T rims, missing roof rack, that's mine. Anyway, SLVRBLT, hope you have a safe trip and Merry Christmas! :drive: :mullet:

Same goes to you :biggthump I'll be with my dad so i'll probably be in the slow lane :cussing: I'll be heading out of Ventura so I'll have a little head start :drive:

You driving with your dad? Just picked up my father-in-law from LAX this morning. He just told me he has a prostate condition so he'll be using the bathroom often. :cussing: Damn! Now I know we'll get there longer than it should take...all those bathroom stops! Take care!

I know the threads been kinda off track, but I have over 210K on the Dak and since the day I got it its had nothing but Royal Purple and K&N Oil filters in it! I change it once a month cause of the distance I travel, but that can be anywhere from 4K to 5K so thats about what I'd do! :biggthump

Joshua,

I too have seen Royal Purple at Pep Boys also and never bothered to try it. It is very expensive. I've always used Mobil 1 myself as it's expensive enough for my pocket book. I have wondered how they compare though. Anyone who wants to give us the scoop.

For your cross country trip I usuall keep 35 in the front and 41 in the back according to the instructions on the door. Doing this it's give me 21.2 on the highway but it's not easy to do but it can be done.

Now and then I still think about trying an engine treatment in order to increase MPG in my "D". I've heard all the pros and cons of doing this but now a days can one stand to lose anything at this point?

Hey RimFire,

Just a little correction. We're only driving up to the Bay Area. I'm not much of a long distance driver so you'll never see me driving cross country. Maybe when I retire some day. But that won't be for a long time!

You mentioned the tire pressure for the front and rear to be 35 and 41 psi, respectively. Does this only apply to the factory tires? My stock tires were 255/65/16 but I've since been running R/T rims with 275/60/17 Falkens.

As far as Royal Purple oil, too expensive. I'm gonna use another less expensive synthetic oil next time.

Thanks for the advice!

If your going to be out on the highway, crank the air pressure near max. The tire will wear better, and you'll have less of a 'contact patch' thus less resistance, better milage (true only by like .5 MPG er so..) but still better. I run mine at like 32 Lbs all around. If the max pressure is like say 45 PSi on the tire sidewall, I'd run like ~40.

Royal Purple is expensive. I can't say that it's any better than any other synth for any reason. I've heard that to be called a 'synth oil' you only have to have a certian percentage (like 60%) synth! Royal Purple (Unlike Mobil 1) is 100% syn. I run mine for around 6K. Filter too. Never had any problems. I also get it at 10% over cost (thanks to Napa) so it's only like $3.40 a quart.

[Jecht]

hate to tell you but mobil 1 is a pure syn oil. you better check that again. castrol syntec is not a 100 % syn. the only pure syn is the 0w-30 german castrol. .

mobil 1 is a group 4 basestock and is 100% syn oil. where redline is a group 5 basestock which is better than group 4 but you pay alot more. group 3 and lower are your reg oil basestocks. so what you posted is wrong and you should edit it so people in here dont take it as the truth. so you should do some research before posting stuff online. I pulled all this info off of bobistheoilguy (http://theoildrop.server101.com) . if you still think M-1 isnt a 100% pure syn oil. go in there and post that but I warn you they will blast you for not doing your homework :rofl:

[scentralpirate]

while the family and I were traveling cross country this summer I had scheduled to change oil I went from RP to M-1 because I couldn't find any royal P in stock anywhere.

My observation was that the royal purple held up far better at 4500 mi. it looked less polluted and felt more viscous than the m-1 after the same amount of miles. I know sticking ones finger in your oil is not a very high tech method of comparsion. :jester: but sometimes you cant help it. :banana2:

needless to say I dumped the m-1 in favor the royal purple once we got home. and plan on keeping it.
