Oil Change Advice

[matthewbellamy]

Well its about time my RX7 deserved an oil change. already ordered a HKS oil filter so just need oil, is there any oil that you guys reccomend? Also how much is needed? Where is the sump? Is there a sump?
 
Also where in the car do you fill up the oil because there are so many screw tops everywhere i dont know which one it is? If someone can point this out for me that would be great
 
I would be able to provide you guys with a pic of my engine if it helps?
 
Thanks :WaveBye

Matt - there are FDUKIN hundreds of threads and post about oil / changing the oil... the search button is your friend
On this occasion, I\'ll direct you...... 5W-30 mineral oil - cheapy cheapy is fine
Of course there\'s a sump! and the drain nut is on it
Fill up via the oil filler neck - directly in front of the throttle body

...and cancel the order on the ridiculously overpriced oil filter, and just use Halfords/Fram/AN Other.

Oil cap is on the passenger side of the engine, just behind the strut brace.

Or even a Mazda OE one.  They are only £6.05+VAT!

Thanks for the help guys! I should have really searched on the forum i didnt realise im still new to this..

Looks to me like you have a nice red HKS oil filler cap :-)

Use 10/40 mineral oil not 5/30.

Hi Ows - Yes you are right its a genuine HKS oil filler cap, i have gone for the HKS oil filter aswell just to match haha!
Hi Carl - Thanks mate i will go for that oil, i was told it would be better using mineral oil rather than semi synthetic. Do i need about 4.5 litres of the stuff i presume?
Also Carl im not too sure whether you are aware that my RX7 is having a bit of a boost problem when accelerating as it gets a bit jittery if you put your foot down, if you gently ease on the acceleration she seems to be run fine but the pull doesnt come until much later (like a delay) the helpful guys on here presume its down to a boost solenoid failure. Im having it in WGT on 25th June and they said they would need to dyno her (im a little worried about this as i read RX7\'s dont like the dyno) do you think thgis may be the problem? If you need any more info just ask! Your expertise is always welcomed mate.

Matt, the lad who sold you the car has only just changed the oil so i wouldn\'t rush to much to do it. He used Halfords mineral oil if you need to top up :Thumbs-up

I agree with not bothering with the overpriced oil filter, I have a generic oil filter on the car, it won\'t be on there for many miles (usually change oil every 3-5k miles) also look for a \'fumoto oil drain valve\' which is basically a tap for the sump, it replaces the sump bolt and means that I don\'t even need to jack my car up to change the oil, just put the container under, reach under, open the tap, drain oil, close tap, refil and replace oil filter don\'t even bother with gloves as theres no mess

Thanks Mitch, I\'m gonna have to get one of these, same all that messing around. Where did you buy it?

I got mine from the states as they were hard to get when I bought mine, it seems you need an F-106 (you can see other options - some have an extended nozzle)

I just have a regular one on my FC, not sure if the sump is different on an FD though.

I would check ebay, as there might be more in the UK now

Hey Dave, i saw what you have wrote about the previous owner has already changed the oil.. when i inspected the oil it was completely black and looks like it had only been topped up not a full oil change. I have opted to do the oil and the filter and sparkplugs myself that way i know they are definitely done (just for peace of mind) I stil cant find those damn blasted sparkplugs though, i found one but no sign of the others..found everything else though lol. does anyone have a photo of where they are please?

As in you can\'t find replacement plugs (mazda rotary parts) or you can\'t physically find the spark plugs on the engine? All 4 are on the passenger side of the engine, can be quite tricky to get to - they are on my FC as I have a massive ABS pump in the way lol perhaps just trace the HT leads down?
