when chaning my engine oil from the factory one to royal purple, its safe for the remaining left over oil to mix with the royal purple right? so on next oil change, i drain everything out and will have a more pure royal purple.

should make no difference when mixed a bit right?

I would read all the fine print on the warranty. BMW recomends certain types of oil, and you could have warranty claim problems in the future if that is not one of them.

there should be no issue with mixing the two unless it explicitly says so on the Royal Purple literature. Oil is oil.

Now, as for the warantee issue, I think the other guys are right. To fully avoid any warantee issues, it is best to stick with a BMWLL01 or BMWLL04 rated oil.

Two examples other than BMW High Performance Synthetic are Mobil1 0W40 and Castrol Syntec 0W30... they are both BMWLL01 rated. Amsoil 5W40 is an example of a BMW LL04 oil that is sold in North America now.

Any other independent oil tests? The Australian test in the commodores rag found that the Australian oils -- RP and Penrite -- were much better than the accepted dominant players -- Mobil, Amsoil, etc.

There's been a bunch of posts re the oil topic but its been consistent in that you can't go wrong sticking with oil with the BMWLL01 or BMWLL04 rating. That ensures the viscocity and the detergent ratings are proper for your engine. I've read other forum members post using Royal Purple with no problems. But those guys normally track their rides and change the oil every 3k or 5k.

Unless you're thiking about tracking your car, you'll get no real benefit from using non BMW approved oils so might as well just play it safe and stick with the OEM stuff.

the reason i was thinking about switching is b/c royal purple made a special 5w-40 forumala for euro cars specific.

If it has the BMW LL04 rating that is what I will be using. I sent rp a query.

It's really purple...I use the RP Race 11 in my Stock Suspension Drag car.

Should make little difference. Royal Purple, Redline, AmSoil, Mobil, all sell good product. As long as the oil meets BMW longlife specs, and isn't too far oustide manufacture specs for viscosity, use whatever you want.

What are you hoping to improve by using RP vs. the OEM synthetic oil?

And BMW designs the engine to use specific oils that it recommends. Why not stick with those?

Because there are oils that outperform (protection, gas mileage, power) the franchised (Castrol) oils. The test results on RP are significantly better.

Less than a year ago, Shiv posted an article done on all the engine wear and tear using the leading oil brands and after reading it, I went and bought 7 quarts of Royal purple. I think Elf or Redline was the best. Mobil, Castrol, etc turned out to have poor protection.

what is the color of redline oil? is it consistent look, feel, etc wise compared to the bmw oil? it says for the 5w-40 it reduces turbo lag and stuff lol. never heard of elf oil though. most people go with rp>redline.

I've never used Redline oil, so I googled it. Apparently its red, lol. JDM tuners love Redline and Royal Purple. As far as Elf oil, I think its big overseas, but I was wrong. Elf fell in the overrated category as well.

Here you go man, it took me a while to find it since it was a year ago:

Royal Purple and Redline have always been top products. I haven't been using them because the don't have the little "BMWLL01" or "BMWLL04" on the lable and this could be an issue with Warantee should anything go wrong. I will consider using them after my warantee is expired.

That article was very interesting...I just wish it compared more than the one test! Seeing performance in extreme cold and heat resistance would have been nice... also having a study on each one's ability to fight contaminants such as sludge,etc.

Royal purple definately seems like good stuff!

As suggested, the oil should say that it meets or exceeds the manufacturers requirements. For instance, I am a Mobil 1 fan and here is what I found on their web site. Royal Purple should have a similar claim.

Mobil 1 0W-40 meets key industry and car builder specifications for:

Mercedes MB 229.5
BMW Longlife 01

Porsche Approval List 2002
VW 502.00/505.00/503.01

GM-LL-A-025 (gasoline)
GM-LL-B-025 (diesel)

ACEA A3, B3/B4
API SM/CF

I read an article that basically said that a lot of "FULL Synthetic" oils were really not 100% synthetic but had highly refined non synthetic components. Mobil 1 was one of those listed( I have used the Mobil 1 products and think highly of them). I believe Amsoil, Royal Purple, Motul were listed as actually being 100% synthetic. That being said, unless you are racing, most of the BMW approved oils and almost any other name brand calling their product "full synthetic" will probably give you engine extremely good protection. I changed my oil and used Vavoline SynPower Full synthetic oil .http://www.valvoline.com/pages/produ...asp?product=19 I'm not sure whether it is a BMW approved product but I don't expect to have any problems. I think there is a greater chance of having engine problems from letting the BMW oil in for a full year than changing out the oil every 5-7 K miles, whatever brand of so called FULL SYNTHETIC oil that you use.

Yeah, Royal Purple does well in that particular test, but when I inquired about it at the local lube place, they told me they don't carry it as it's not SAE approved.

So on the one hand, you've got people who use RP and tests that make it out to be the greatest oil available, but on the other, you have a product that hasn't been approved by SAE. Makes me wonder why (if RP is so great, why haven't they gotten SAE approval)?

[DBville]

As others have said, you risk losing the engine warranty by not using LL01 or LL04 oil. Given that the BMW oil is relatively cheap, about the same as Mobile 1, before the BMWCCA discount, I will use it. I have heard that either RP/RedLine/Amsoil (don't remember which one) did not get their oil tested to LL0x specs due to cost. They might meet it, but might not.

Unless you are doing some serious track work, and have a specific reason to change, I see no reason to not use the BMW oil - meets specs, reasonably priced, and preserves warranty.
