- Hi I have a Scion tc 2012 thats 41,745 with synthetic 0w-20 Genuine toyota oil that i got from the toyota dealership last time i had my oil change done with them. They said its good for 10k til i do an oil change again. But I heard its better to do it every 5k miles. so I have done my research and decided to change it to Mobil 1 synthetic 5w-30 which i heard most of the people use, and i will do this myself. Before that, this is also my first DIY for oil change, I would appreciate any advice. Also is there any special kind of draining/cleaning since im switching from 0w-20 to 5w-30? So any advice would be appreciated before i do my oil change in a couple of days.
First off, let you know that Mobil1 has been known to burn-off and make you think you have an engine burning oil. My research shows it has something to do with the volatility of the oil and how much burns off at higher temps. Just so that you're aware of that. It doesn't seem to matter which weight oil is used.
Now the bigger question is, can your engine even handle the 5w-30 oil. I would say 5w-20 would be ok, but the 30 makes me wonder about your oil pump and what the engine is spec'd for. I know the 1st gen can do 5w-30 or 5w-20, but can't move to a Ow-20 like you can. Something to think about before you do this.
As far as draining the oil, it's simple, get a drain pain, remove the drain plug, let it drain (about 20 minutes) into the pan, put a new drain plug washer on the plug, replace plug, only snugging it down nothing tighter. Then removing the oil filter, might need a special tool, I like this one, very nice, plus not expensive!
It's $6 at autozone, and it will make your life very easy in removing your oil filter. Just attach a 3/8" extension to the hole. and twist.
The oil filter for your car, I'd use the Toyota brand one, get at the dealer for like $4-5. Very good quality, don't waste your time with aftermarket the level of quality is all over the place. Everytime I've found a good aftermarket one, then they change the design, etc.. tired of that so I just stick with the Toyota one.
I also fill up the oil filter with oil first then spin the filter on. I believe the 12 is just like the 1st gen, it's a spin on vertical filter. make sure the seating surface of the oil filter is clean. Then spin on the new filter, hand tighten it only. When it gets tight, you're done.
I also use jackstands to jack up the front of the car, plus with the front raised it makes the oil come out better.
Then just fill up the oil with what it's spec'd for. I know the 1st gen is 3.5-3.7 quarts. I think yours is 4, but just check. Then once all is full, I take the car down off the jackstands and start the car, let it run for a minute or two. Shut it off and check the level on the dipstick.
After that, start it again, let it run, check for leaks, you should have none. there ya go!
but I would look at another brand of oil instead of mobil1, maybe look at the 5w-20 from Toyota. It's really good oil. Toyota told Mobil what they wanted and Mobil made a custom oil for them. Yes, guys have sent the oil off to Blackstone Labs to have new oil analyzed, that's how we know it's different.
