The Toyota filters are great.
Go to trdsparks.com and get them in paks of 10 for ~$35.
Get the "yzzf1" units.

i got about 17,500 miles on my car now. and i didn't know about or learn about synthetic oil until a couple days ago. so is it too late too change now or will i still feel the difference and have an affect on the car?

i know it won't have an effect after 1 oil change but say 2 or 3???

 

It's not too late.
Go ahead and do it.
It's not like you'll get a new car using it, but mileage can increase slightly and the car often feels smoother.
It's just a better oil, IMHO.

If I have about 21K miles on my xB, will synthic oil cause any problems to the engine or whatever? My oil change is coming up and I want to switch over for added protection............I'm going for Mobil, Redline, Royal Purple.

 

Nope - in some older, high-mileage cars, you might have an issue with a leaky seal, but not on your Box.
Go for it and enjoy.

Scott

 

For those who are late to know. It just means you broke your motors in longer. You'll still get the added benefits
Forget the expensive stuff. Mobil 1 is all our little motors will need.

 

Switched to Mobil 1 5w-20 at 11k miles.
Only put an additional 1500, maybe 2k since.. runs great.

Save some money, do it yourself, and stick with toyota filters.

 

As mentioned you can change to synth at any time and back if you want. The only time I have heard of a real issue was on older porche case seals.. which were known to leak anyway. Some people reported terrible leaks right after they changed to synth on higher mileage engines. But the data is pretty scarce and could point either way. Other than that I have never heard of an issue. I have taken cars with 100,000 miles on them and changed to synth.

 

Synthetic oil will not make any immediate change or difference in the way an engine runs.
I have switched back and forth for many years on many cars and bikes. I break in on petroleum oil, change to synthetic oil, then after 5-10 years figure the vehicle is no longer worth the expensive oil.
Toyota recommends the oil grade that is marked on the filler cap. My xB was made in Feb 2006 according to the mfr's sticker on the door jamb, and the filler cap says 5W-30. The change to 5W-20 came later in Feb 2006 according to this tech bulletin:

Technical Service BULLETIN
TSB #ENG01-06
March 29, 2006
Title: ILSAC GF-4 ENGINE OIL RECOMMENDATION
Models: All ’06 – ’07 Toyota & Scion

Toyota Motor Corporation manufacturing plants have begun using ILSAC GF–4 engine
oil. This engine oil is recommended due to its superiority in terms of fuel economy and
engine protection and due to its benefits for both the customer and the environment.
ILSAC GF–4 can be used in all Toyota and Scion engines.

Applicable Vehicles: 2006 – 2007 model year Toyota and Scion vehicles.

Recommended Engine Oils: ILSAC GF–4 SAE 5W–20
This oil has been set as the Toyota genuine engine oil, starting in February 2006 for
the U.S. This oil is superior in terms of fuel economy, engine protection, and cold
starting performance.

NOTE:
􀀀 The recommended viscosity grade for this oil differs according to vehicle model.
Use the recommended grade specified on the oil filler cap or in the Repair Manual
or Owner’s Manual for each vehicle.
------------------------

So why doesn't Toyota recommend 5W-20 for pre-Feb 2006 xBs?
Might be some slight internal difference in the oil pump or passages or clearances.

My TC was manufactured February 2006 as well. This is why I made the switch to 5w-20.
As far as I know, there weren't any changes made during the month of Feb 06' that made the switch critical.. I read it was something with the fuel economy. At any rate, even though my cap says 5w-30.. I'm running 5w-20.

I wasn't saying the car ran any better with synthetic, was just saying it runs great.. it does.

Synthetics are better oils, and I don't mind paying for quality since I've invested so much in the vehicle already.

 

If your tC is an '06, it doesn't matter when it was made.
All '06 and up can use 5w20 - ALL.

Scott

 

So, I guess its ok if my 05 xB uses 5-20w? Toyota needs to make sense the first time around, lol.

 

What is there about TSB #ENG01-06 that does not make sense?
It says use 5W-20 if your car was made after Feb 2006 and says 5W-20 on the filler cap.
If there needs to be a second time around, how should the TSB be clarified?

As to whether you can use 5W-20 in your 2005, of course you can. But normally you trust the vehicle manufacturer to recommend what they feel is the best grade of oil for each engine they make, and apparently there was a change in Toyota and Scion engines in mid-Feb 2006 associated with the recommendation of lower viscosity 5W-20 oil. Changes that could make use of such thinner oil might be better ring design, tighter cylinder clearances, an improved oil pump, etc. Maybe using 5W-20 in an older engine would result in an increase in oil consumption.

 

im sure this has been answered somewhere but what weight oil does the dealer use? do they change the weight if the s/c is on the car?

 

What do you mean weight? How much oil the tC can hold? 4 quarts.

 

what type 10w30?

 

10w30 Royal Purple

 

There is a place by my house that I take my truck to - they use good products and have $24 oil changes - Im not going to the dealer for $37 oil change. So 10w30 is what they were using? .... and non-synthetic ...right?

 

5w30 for '05 and '06s
5w20 for '07s

 

$37 is very pricey for non-synthetic. DIY oil change with synthetic costs ~$20.
