Found something on the xB forums but nothing here...
I drive an '06 tC, so 5W-30. Anyone use RP in their tC gimme feedback please!
Also, I've used Mobil-1 full syn for as long as I can remember (70k on engine). Sending a sample from my oil change today to Blackstone Labs. Was at 3,026mi (yes, I know syn can be run for longer but I like the 3,000 mile rule). Planning on sending a sample from my next oil change also to compare the two. Really all I'm looking for extra feedback on an approx. # of miles to run the RP in ratio to 3k on M1-syn. I've read 8-10k miles on RP in a couple places. Planning on getting the TBN test for both samples also.

Also I accidently put 4qt 8oz oil into the crank, 2oz over what spec is. Normally I wouldn't worry but the Royal Purple oil filter is smaller than the OEM toyota one. Oil looks over filled on the dipstick, but I haven't taken the car anywhere yet. Should I drain a little oil just in case, or not worry about it? Thanks in advance.

 

I wouldn't worry about it, I did the same thing by mistake and it is about 1/4 inch over the full line. I'm turboed though, so the extra oil might be ok. I'm currently running RP, but from the oil reports it doesn't seem to be much better than cheaper syn oils. I would like to see the difference between RP, redline, PP and amsoil in our engine (2az-fe). From what I've seen, Pennzoil Platinum seems to be pretty darn good. Just don't know how efficient it would be under extreme loads (turbo), like how it could prevent a spun bearing. It's just soo cheap

P.S. Mobil 1 extended performance oil filter, Royal Purple oil filter and K&n oil filters are exactly the same, only difference is can color and the little nipple on the K&N. I will be opening a K&N and a mobile 1 EP soon with pics.

 

I have never seen this so called Mobil 1 filter in any parts store I go to. Or K & N. Where do you find them besides online? Pennzoil Plat I looked at hardcore but I wasn't convinced past RP I guess. Thanks for the feedback. I posted same thing on bobistheoilguy I hope it helps too. Mainly I'm just looking for something to match cost. Buy 1 oil change and spend money on 3 but take 3 times as long to do it again. But then again, Mobil1 is so solid and cheap enough to buy every 3-4k miles.

 

RP burns quick when doing high revs. its proven. my friend with his stock k20 hatch needs to refill oil like every week with some. maybe its too thin?

 

I'll check the level every week see if it goes down. I don't really high rev too often, but I am very spirited at times.

 

No point in using synthetic if your going to be changing your oil every 3000 miles. Stick with dino oil

no your friend has an oil leak somewhere. There should be absolutely no reason he needs to refill every single week. Even on a swapped engine.

A good read for you scionlifers

Spirited driving? truckers drive easily 1000-2000 miles a day. Pushing your car to 6200 rpm and downshifting for a couple minutes is nothing. Unless you pretend to be mario andretti all day

also another good read

Lo Bux Racer who also sends his samples to blackstone labs. Bottom line, no point in changing oil so often (given certain situations might i add)

 

And that shouldn't be a problem for the tC considering it only revs to 6200.

 

that can't be true. Back when I was running PP I used to have to add half a quart before every oil change. So far with RP I haven't had the need for that and I have been pushing the intervals even more.
Ur friend has either a leak somewhere or bad blow-by, I don't know what else to think of.

OP, u can get the mobil 1 ep filters at autozone and even some walmarts. If ur turboed u could go with any of the three I mentioned or a wix filter/napa GOLD. They have a higher flow than say pure one, but still filter just as good.

 

oil leak? its a stock k20! i was using rp and i checked my oil like 2 weeks ago and it was fine. this past sunday i turn my car on and i hear a knocking noise in the motor. 2 days later i take it to the dealer. the motor had no oil and now i have to replace my whole short block. my other friend who has a h22 was also using RP who had the similar problem just 2 weeks ago except his motor actually blew! i personally think it burns quick. or maybe its just my bad luck. now im gonna be checking my oil every other day! atleast i have ptuning building my motor in a couple days!

 

I've been running RP for the last 2500 miles and my oil level hasn't changed at all.

 

been running RP since after the complementary oil changes by the dealership. I have had absolutely no problems ever.

 

We ran RP on my girl's TC the first time, but then switched to Amzoil and instantly felt a difference in the cars responce. Amzoil is cheaper once you also become a "Preferred Customer" which in itself pays for itself over the years. I run Amzoil in my XB and her TC.

did you change the weight of the oil? Shouldn't be that much difference between the two oils.

 

Same weight it is the different viscosity used in the oil. It isn't a huge noticeable difference just a hair more responsive.

Just 2oz. over shouldn't be too bad, should be barely over the full mark on the dipstick, like 1/16th inch.

However, too much oil can be VERY bad, causing seals to blow, often expensive to replace, so people should make sure to not over fill when changing or adding oil.

 

That's the thing, I know 2oz overfilled oil isn't much at all, but I took into consideration the size difference in the toyota to the RP filter. Since RP's ia smaller, maybe it would be 2oz + however much difference is in the capacity for the two filters? After this week I'mma check to see if the level went down at all. If not I might just drain it a touch just to be safe. Is there a siphon kit or anything you can buy to extract from your dipstick tube?

 

again, a stock k20 should NOT be burning oil that quickly. Guaranteed you have a bad seal somewhere. My friend runs RP on a base model RSX no leaks whatsoever. Just because it is a stock engine has nothing to do with the way it seals. Something must have been overlooked during the swap. Hondas, hell, 4 cylinders period running NA can NOT be burning through oil that quickly regardless of the "spirited" driving

 

another good read by a renowned biochemist who studes motor oils specifically. everything you need to know about oil down to the nitty gritty.

this was takin from a yoursciontc thread, info from lo bux racer

 

I remember seeing one years ago that had an inline pump you power with a hand-held drill, not sure but would think there'd still be something like that available. As an alternative, you could just manually siphon it, just need a piece of tubing that'll fit (windshield washer tubing might be small enough?), which you should be able to locate at an auto parts store.
