What’s going on… Didn't notice a 3IS oil change DIY yet so thought I'd document mine..
So my old man and I own a little service shop and I decided to do my first oil change on my 2014 IS350 RWD ( non-fsport.. with f-sport front bumper and wheels )
I’m all about doing stuff myself obviously so here we go!

Here’s my equipment:
Oil Filter (Element - From local Toyota/Lexus Dealer)
Oil Filter “F" Cap Wrench (Online , Local Part Stores)
Oil Drain Container (I Used my old pro-grade one)
Funnel
10mm Socket (C’mon, you’re a car guy, right? :P)
14mm Socket (Remove Oil Plug)
6 x 1 Qt of Synthetic Oil - 0w20
Shop Towel(s)
Some kind of Shop Gloves

Note: Please be advised that I obviously lifted my car with a professional-grade lift. This will obviously not be the case with you. Please
be careful and maintain full precautions while lifting your car up with a jack, ramp or stands.

I got the oil filter from my local Toyota dealership. Oil from my preferred CarQuest.
(it's fully synthetic and I've trusted this particular store for XX years)
Feel free to get the oil & filter at the dealership (Lexus / Toyota)



Step 1: Lift the car up. Make sure you lift it in the right place…. Like so.. (Put those gloves on unless you do this on the reg!)
Notice the pieces of wood under my wheels.. Had to do it this way since I'm lowered on coilovers.



Step 2: Unscrew the screws that hold the plastic cover underneath your IS.



Step 3: Locate the screw for your oil pan. Grab your 14mm socket wrench and unscrew. Be aware of hot oil if you recently drove!
Here’s where you can notice how dark your oil is from all that driving.



Step 4: Once Oil drained from screw…. Wipe nicely and screw back on. Screw tight but make sure not to go wayyyyy too hard.
A big tip would be never to strip that screw… ever.



Step 5: Grab your “F” Cap wrench and locate the Oil Filter… It takes a bit to learn how to use it properly if you haven’t ever.
Slowly unscrew it with the wrench and let the oil pour into the drain container.
There will be A LOT of oil that comes out of this one. Feel free to throw the old filter in your drain container also.




Step 6: Once the oil is fully out, grab your brand new LEXUS / TOYOTA OEM oil filter and new rubber seal. Make sure you have a new rubber
seal too. You should never use the old one.

Step 7: Thoroughly clean out your old oil filter container and remove the oils oil filter along with your old rubber seal like so..

Step 8: Once cleaned and removed.. Grab your new oil filter and easily slide it onto your filter container.



Step 9: You can put the new oil filter seal back on now. Grab some oil onto your finger and rub it onto the rubber oil filter seal after too.



Step 10: Carefully screw the oil filter back into its original position with your hands, then fully tighten with your “F” Cap tool.



Step 11: Make sure all is tight…. Triple check that everything is looking good under your car. You will probably have to wipe excess engine oil that may be on the side of your engine block. Then you can grab your underbody plastic pieces and screw them back on with original screws.

Step 12: I am now lowering the car to get to the engine bay to put the new 0w20 Synthetic oil in. Let’s Go!

Step 13: Locate the Oil Cap… Unscrew and get a little funnel to start pouring!



Step 14: Pour about 6.5 quarts in… It’s a thirsty one!



Step 15: Screw the cap, while around the area, triple check everything.

Step 16: Start your IS for a second, then turn it off. Now check your engine oil levels with the dipstick!

Step 17: Time to reset your maintenance light.... Go into your car settings from the steering wheel and navigate to maintenance. Click reset!

Congrats… You’re all done.

 

Nice write up!! thanx... will be doing my own.

 

Good write up. Few questions:

Does anyone know if our cars will be able to go up rhino ramps on stock suspension?

When doing the oil filter, is this vehicle like the RX350's setup where you can plug a plastic drain plug into part of the filter cap to attach a hose to drain the filter without making a mess?

 

Great write up! Can they stick this to the DYI thread and frequently asked questions. I noticed nothing is on there.

 

i use 5W-30 Castrol magnetic !! great write up

 

great write-up! Was there a crush washer on the oil pan bolt, btw?

 

Yes, There is a washer there!

 

Bump

What a great writeup!

I'm also interested to know if our car can go up a rhino ramp workout scraping the exhaust?

Also, do we only have to remove 1 panel to get access to the oil filter housing? And do you need a special tool to remove the panel?

Thanks in advance!

 

10mm socket is your best friend.. grab a ratchet too or power drill w/ socket extension

 

Thanks bro!

 

great guide! thanks for sharing

 

Yes, thanks for the guide. I like to have my oil changed every 5,000 miles. The dealership gives me a hard time every time I have asked for the extra change. Now, i will just do it myself.

 

Fantastic write-up!

 

Agree, and done!

Would be good to know if this applies to the 250 as well.

 

Just got confirmation that 2014+ IS250's also use 0w20 synthetic oil.
This means this DIY works for IS250 too!
