I got a case of royal purple for $80 at pepboys, and I have three new mobile one filters laying around.

 

FYI - RP filters are made by Champion Labs (good sh*t), but they also make the K&N, Mobil 1, Mopar, Champ, Luber Finer, VW and STP to name a few to the same specs that are less expensive. They are also manufactured right here in the good old USA - most at their Albion, Ill. plant.



Beware of the Mopar branded ones at retail stores - I'm told (unverified) that the Mopar contract with Champion Labs is for dealer only filters and the retail chain (ie: Wal Mart) are contracted with Fram...

 

Im running Quaker State Q Power Full Synth, 5w-30. I have a Mobil-1 filter as well. Change it every oil change.

 

thanks guys,


great info....,
I guess I will give'er 8000 km before I crawl under......

great forum,


Cheers,

The best.

 

C'mon guys - I thought the whole point of synthetic was extended intervals. I've been changing mine every 10k miles or 16,000 km for the Canadian members here.

 

holy crap 16000 km, i wouldnt dare i also change mobile 1fullsyn 5-30 every 8000km with mobile 1 filter

 

Agreed

 

I have religiously changed oil every 3 months/3000 miles on every car I have ever owned (which is a lot). Going to 6 months/6000k is like scraping fingernails on a chalkboard for me. I'm only on my second oil change since switching to synthetic. I think this next time, I will send a sample off to have it analyzed. Maybe I will increase it then.

 

I go 6k and have had my oil analyzed about four times, twice in my truck. Once with Valvoline SynPower at 6k and once with RP at 6k (I really wanted to see of RP was any better). BOTH times my report said I could run it another 3k and have it retested. I still do 6k changes though.
Based on that, I'd say 10k is probably doable but I'd get me some tested at 10k at next change to be sure - it only costs $25. Blackstone will send you the jar and label for free if you get on their website...
