wooo WOOO!

 

I wouldn’t trust Midas changing or flushing my oil

I also heard its not good to flush out a new engine

5W-30 is good but wouldn’t go with synthetic

 

can you explain why?

(before people complain that your answer is to vauge )

 

What's everyone's opinion on when to switch to synthetic? Some say 1k is good, others 3k, some 5-6k, and there are those that say you shouldnt change for the first year. You have some arguing that there are blow by issues and that the pistons rings won't seal well....but at the same time some cars come with synthetic from the factory. I know this is an old topic but I'm just curious about what us Hawaii folk think.

And Dave....I'm sure the flush can only be good...unless you got some guy running too much pressure!! I've heard some stories about oil and trans flushes but not I'm not sure how credible they are. As for me...it's time to change the oil...I think I'll use dino at ~1k and 2k, and I'll switch to synthetic at 3k after that. Probably Mobil1 but not written in stone yet....I used Syntec for a long time...

 

Ok because I'm lazy....any of you STI guys know the Fram part # for the STI, or if it uses the same filter as the WRX?

I plan to switch to Mobile 1 5W-30 on my next change. Since I plan to take it to the dealer I'll get Ed's take on it. I switched over to Mobile 1 5W-30 on the Wagon around 6K miles.

 

Let's just say that if........

Mobil1 is recommended for use by the manufacturer in......

1) Vettes

2) 911s

3) EVO's <----it's on the oil cap

4) many other Bad A$$ cars.

That it's good enough for my STi.

I''ve used Mobil1 in all the cars I've onwed and have never had one problem.........EVAR.

 

Shoulda poured it in your WRX transmission. j/k !!!

... on the topic of when to switch to synthetic, ..... IF you're motor is completely broken-in at your first oil change, then I'd say things would be okay. BUT if the rings aren't totally seated/sealed properly, switching to synthetic would be a bad idea for some of the reasons mentioned earlier.

Personally, I would never switch to synthetic until after about 3k or so, .... but what do I know.

 

The reason we flushed with syn, was to try and get all the dino out.... Oh and we reused the old filter for the flush, just drained it and then put it back in for the flush. After letting car idle for a bit, and couple light rev's we shut down, drained oil, changed to new filter and filled with syn again. Might have been over kill but hey you only switch to syn once right ? It must've done some good...14.151 up-pipe, downpipe, intake, stock-boost....

 

yeah with room for improvement?

 

I hope....hayabusa here I come !!! nevermind...don't got the funds
