Trying Out Royal Purple

Nytemare · June 16, 2007

So I changed my oil tonight, figured why not give it a try. After reading some reviews on it I figured I may as well.

I'll give it a couple tanks of fuel to see if it helps there. I don't notice a power gain yet, but I did just come from a 4 cyl car to the truck, so the power is still new to me, and even if i did pick up a couple hp I don't think you would notice it anyway.

I have noticed however that Oil pressure is higher when I have my foot in it, and its more stable when cruising.

I'll write back tomorrow after I Get home from a trip to look at a dog I may adopt. Its going to be about a 200km trip, almost all highway, I'll see if I notice anything and get back.

sounds good. I used to dump 6 quarts of that into my '01 F150 and it made a slight difference in power, was a little quicker whgen I used to race around.

Nytemare · June 16, 2007

So I just got back, I have a new puppy, and i burnt less than a 1/4 tank on the 200 km trip so I averaged about 27 mpg highway. my usual was about 23-25mpg there was a lot of up hill driving as well, so it seems like it may have actually made a difference. I noticed that my temp gauge never went over 100*C though, so there is definitely some truth to the heat claim

Thats awesome, I think i'll be switching this truck to royal purple on the next change. My computers engine oil life is down to 40% and I put in mobil 1 about 2500 miles ago, whatever oil was in it before lasted way longer before it even went down to 40%.

I don't have an OLM, only when I need to change the oil it tells me, but I change it every 3K miles anyway. But RP says it will last to 5K miles, Think I should let it go that long??

Your using a superior oil than what the OLM was even designed for....go til it tells you for sure.

Nytemare · June 19, 2007

Is this what you guys do for maintenance?

I'm just form the old way of OCI every 3K miles, I figured 50% more or so would be a good estimate for this oil.

I have read reviews about the additive (molysolids) not being good for the engine if they were left in too long.

What do you guys think??

I still try to change my oil at the 3000 mark, it just makes me feel better.

Let me know how the RP works in your truck.

I had RP in my LS1 and loved it!

I may have to try it in my truck.

So, after a few days of driving I have noticed that the truck idles a lot smoother and there is less valve train noise. The temps are still down, and my oil pressure is a few notches higher.

I still haven't noticed a diff in power but as I said before I don't think I would notice the couple HP it does free up.

speedracer7c · June 30, 2007

What weight oil would you recommend?

Schmids5.3l · June 30, 2007

I'll be with you here in a few weeks maybe, my OLM is showing mid 40's. I gotta order online tho, only place near here that sells it is a Pep Boys who prices that stuff like it's gold. It sounds pretty good though!

I used 5W30. Thats what the engine calls for.

I like it so far, I have noticed a little increase in power, or so it seems. It seems like it pulls a little harder from a stop now. I really have no comparison so don't take my word on that one. My ass is not a very well calibrated dyno. Fuel seems to be getting better though...getting about 30-40 more km per tank.

I ran it to 5k miles in my old F150, never hurt it & it ran great, soon i'm due for an oil change so i'll be pouring RP in it.

Tyler_LS1 · July 5, 2007

It calls for 5W-30 but that is only for warranty conditions.

Once your warranty is up or get close to 80-100K miles you can switch to 10W-30. even better if you have hot summers.

I noticed less drivetrain noise when switching to the thicker oil.

Once your motor gets broke in and has higher miles on it its ok to use a thicker oil.

bassadict69 · July 5, 2007

For some reason, If I use something other than 5w30, my check engine light comes on. Was in a bind for time once & had the oil changed at one of them oil change joints...they used 10w30 by mistake & it set the light off about 5 miles later. We like to have never figured out that the oil set off the light. Took it back & had them change it again with 5w30 & that took care of it.

Anyone else had that happen?
