im thinking about switching over to royal purple synthetic oil but first i need some questions answered that my searching hasnt yet yielded.


1)how often should i change the oil? 3k?

2)should i keep the weight at 5w20?

3)where can i buy this stuff at a good price?

4)what do the rx8 royal purple users think of it?

5)do you notice slightly better gas mileage/power?

6)what steps should be taken during the oil change that switches out the old dino oil to the royal purp.? besides fully letting the old oil drain? should i dig all up in my oil pan with a spoon and a straw scraping/syphoning out the old oil?

**i read some where it will take several more oil changes before im fully synthetic.

 

3k

5w30

online, just google it.

great stuff.

no idea, if there was better power, there is no way to tell.


all of the answers besides #4 are opinions...

 

i was editing my post while you were responding.

thanks

 

just jack up the car on both sides to make more oil drain from the oil coolers. You're not going to get it all, but in 2-3 changes you will. syn and dino oil can mix without issue.

 

where do you buy your RP oil from?

 

I bought mine off the Internet.

 

It's also available at Pep boys if you have one nearby.

 

well then i guess the innernet is the best source to get out sourced pricing sourced.

i wonder if that makes any sense.

thanks

try them, they are worth about a 20 min drive. excelent prices. i think we got them for 650 or 7 a quart.

i would like to hear some negatives to that oil though. i heard its awsome, but its always more interesting to hear the negatives.

 

For $6.75/qt you can get it on ebay. $81/12qt case includes delivery to you front door.

 

got it now?

beers
