So then after the long research regarding the famous dino vs. synthetic oil I've taken upon myself to do the change.

First try was with Redline 20W 50. Motor was running a bit smoother. Then I read about how some people have said that RP was better than Redline so I was curious to try it myself. Well I dunno what happened, maybe the synthetic oil broke in my motor but my MPG dramatically increased by nearly 50 miles more per tank! I don't know about you but previously I usually get just a bit over 200 miles for a full tank, but now I get way more so I'm happy with the oil.

That is all for now.

Anybody else have any nice improvements?

I don't have any yet... but...

I'm breaking in my motor on good old all natural oil, and once I hit the 2000 mile mark, I'm switching back to Mobil 1. I'll note any changes here when that time comes.

 

i run castrol syntec with a mixture of lucas oil stabilizer. my car seems to idle smoother everytime i get into it. i also blocked off the OMP and ran 2cycle injector oil to the block off plate. . . i INJECT 2cycly injector oil into the rotorhousings onto the apex seals. i also use marvel mystery oil on every tank. . . safety is oh so great. haha

When I switched to Mobil One, my oil temps dropped about 10 degrees. I am hoping that the synthetic will extend my engine and turbo life. There was no change in how the car ran, or the gas mileage.

Changing oil WILL NOT significanlty effect gas mileage.

 

Yeah but in my case I did notice the increase in miles per tank. I always keep careful tracking on my miles/tank and I was so happy that I still had so much gas left when I should have been filling up. And also I was doing semi agressive driving for the last tank so it probably could've been better. Then again every motor is different right?

i simply ask this question because i've been doing a lot of reading and research and came up with these links that have a different opinions on the use of synthetic oil:

http://www.mazdatrix.com/faq/synthetc.htm

btw kinda off topic: for r1 owners, i was also reading that we are suppose to be putting more (or is it less?) oil because of having two oil coolers. the reason being that the oil in the oil coolers don't drain when doing an oil change, and addition to having two in the 'r' models.

Hey, how are you able to avoid interference b/w the turbo oil feed line and the OMP with the adapter plate?

Tom Jerry rewelded the metal feed line and I read that someone else clocked their OMP.

Can you explain?

 

heh quoting myself. been doing a lot more reading on this forum.... and found: i'm assuming the two links i've posted above referring to synthetics bad was maybe because synthetics were really bad 10 years ago when the fd came out. after doing some reading right now, i've come to the conclusion that synthetics are okay to use now since they've grown technology wise in the last 10 years. i myself will probably be putting synthetic in my engine.

Garfinkle reclocks the black round part of the omp when using the stock twins and the 2 cycle oil mod . He does not do anything to the turbo oil line . Rotorbrain has a single turbo , so the oil lines are modified .The reclocking was not needed . A new oil drain was needed if I remember what Gar told me .

 

100% duboisr. thanks for the explanation!!

oh, did david tell you i got the brace in? mmmmmm. . . me likey.

 

My R1 has always taken right at 4 quarts, and she's prolly been through 30 oil changes since I've owned her.

 

maybe this is off topic... im going to change my oil to Mobil1 SuperSyn as soon as i put back my turbo... for those who use Mobil1, do you need to mix with anything else??

 

nope. Like what?

 

i meant mixing wiv some additive!?! i hear some people put some additive to their fuel... but am not sure what it is?

let me rephrase: can i run Mobil1 wivout adding any other addivite or oil?

 

A lot of guys mix 2 stroke synthetic oil in with their gas (about 8 ozs per tank). That's something different entirely. You can run synthetic Mobil1 without any additives at all .

 

it doesnt hurt to run about 4-8 oz. of marvel mystery oil in every fuel fill-up. i do all the time.

paul

 

so why again they mix 2stroke synthethic oil? tanx goodlfella...

 

It helps to lubricate the apex seals....a lubed up 13B is a happy 13B .

 

It's true that the oil capacity of an R1 with the dual coolers is higher, but when you drain the oil you only get out what is in the pan.

Regardless of the type or number of coolers you will only need 4 quarts at each oil change because that is all that comes out of the pan.

 

ahh... that helps a lot indeed... i feel like im jacking up this thread.. hehehe...
