I went to get my oil changed today (4600 miles). They told me that it wasn't due for an oil change until 10k miles. I told them they can pay for and install a new engine when this one burns up.

No offense, and it's your money, but the redesigned engines for 2010+ come with full synthetic and are rated for 10k mile intervals. Engine and oil technology has come a long way, and there really is no harm in going that long between changes if the engine's rated for it. Toyota is loosing maintenance money by going to 10k mile changes, so there's really no reason for them to do it unless the engine can handle it. Even my old 1996 Cadillac was rated for 7500 mile intervals...

football so will you or have you gone 10k miles intervals???in my book i don't care what toyota said or if it's writen in stone i wouldn't even go 5000k miles

I have not gone 10k since I have on 07, and 07-09 are rated for 5k miles with dino oil. I use full synthetic Ifeel comfortable going 6k miles (went 7k last time) between changes. Only have 40k miles on the truck but I don't ever notice a difference in performance after I do the change, even last time w/ the 7k mile interval.

I've seen some used oil analysis on the forum from people using synthetic (Mobile 1 or Castrol Syntec generally) in an 07-09 going 5k-7k miles and in all cases the oil holds up great. Only real complaint I've read is Mobile 1 0W-30 sheering to a 5W-30, but the analysis of Syntec 0W-30 I've seen shows it holds it's viscosity.

With a 2010+ I would go 10k miles, but I wouldn't go past 10k miles since that 10k rating is based off of using synthetic oil.

To each his own, don't want to rub anyone the wrong way, just sharing my experiences and opinions :cheers:

I have an '07 and use 10K mile OCI's on M1 0W40 (A3/B3 european spec) oil and Amsoil EaO filters. I use the same oil and intervals in all my vehicles and have for years. No oil burning and great engine compression = no worries.

Yes you can change your oil everyday, but all that does is make you feel better, waste money and resources IMO.

DEWFPO

Why the 0W-40? Been thinking of going to 0W-30, but hadn't realized anyone ran 0W-40.

 

[football751]

I use amsoil 0w30 and have 22,000 miles on it (the oil that is). I have sent a sample off for analyst and will be changing it this weekend. I will see what the report says and make adjustments accordingly. I will post the report here. I have changed the filter out at 15,000 miles and topped off the oil.

Wow, 22,000 miles. Definitely interested to see how it holds up. That extended life amsoil is expensive, but if you can get 20k+ miles out of it, it pays for itself.

I used to run the Mobil 1 European Car Formula 0W-40 but local supplies dried up. The made in Germany Castrol Syntec is very easy to find at local Canadian Tire stores

Both oils are designed for long service intervals in Europe.

Used oil analysis on both oils prove they work very well in the FJ motor. The M1 0W-40 shears a bit to a solid 30 range, the Syntec does not shear

I also have run Mobil 1 Turbo Diesel Truck 5W-40. This oil does not shear, and also holds up very well. In a mild winter climate, I'd run it year round. For my winters, I'd want a 0W-xx oil

I have also tried Mobil 1 5W-20 and 0W-20. No difference whatsoever in fuel economy. The 5W-20 and especially the 0W-20 resulted in a noisy valvetrain

One thing about a cartridge oil filter is that any debris is very evident. With a canister oil filter, you have to cut it open to inspect.

I did the first oil change at around 2,500 km as the used oil analysis indicated 0 TBN, very high nitration, oxidation, etc. I'd like to see more used oil analysis on the +'10's before 5,000 initial miles so we can establish a baseline

Moderators: how about a separate section in the Maintenance just for used oil analysis?

So between the Castrol 0W-30, M1 0W-40, and M1 5W-40, which would you recommend (all synthetic of course)? I live in central Texas, so summers are 95F+ and winters are usually 20F+, so pretty mild. My drives are usually only 10-20 minutes and just around town, with some highway driving. I'd like to run the same oil year-round.

And I'm assuming all 3 of these would be better than Castrol Syntec 5W-30 (what I run now)? I like to go ~6k miles between oil changes. Currently have 40k miles on my FJ.

 

[football751]

I'd probably run the M1 TDT 5W-40 all year round. Really don't consider +20 F "winter."

Based on testing, the made in Germany Castrol Syntec 0W-30 is the only Syntec I would run. I also wouldn't be afraid of it in Texas.

Autozone is having a sale on M1 right now, so I'll pick up some 5W-40 for my next oil change. Thanks for the advice :cheers:

Will the 5W-40 help with the "tickiness" of the engine?

Would the M1 0W-40 or 0W-30 work just as well for me, or at least better than Syntec 5W-30? Local store with M1 oil change special doesn't stock M1 5W-40. It's a special order item which I'd rather not mess with, but will if it's really the best for my situation. And the store with a Syntec special doesn't stock 0W-30.

Thanks for all your help :cheers:

 

[football751]

Any thoughts on the Syntec 5W-40? Says it's made to meet the needs of BMW, MD, and Porsche. Or will it not sheer to a 30 weight and be too heavy?

 

[football751]

IMHO, I think it is too heavy.

Haha well all I need is an opinion :rocker:

Now I'm just trying to decide between Mobile 1 0W-30, 0W-40, and M1 Extended Performance 5W-30. All come with the extended performance M1 oil filter. I'll probably run the EP 5W-30 for 10k miles and either of the other two for 7500 miles, unless any (or all) of them could go longer?

 

[football751]

The M1 0W-30 would be close to the Syntec 5W-30. The 0W-40 is a better oil, at least I had good results. It did shear a bit after 7,700 miles, to a solid upper end 30 range

I wouldn't use a 5W-40 up here in winter at -40. The heavy duty oils designed for diesel service, they say no colder than -30 C

Down here very coldest we see is +15F, and that's extreme. You recommended the M1 5W-40 for me, but that's hard to find here, so I'm wondering how the Syntec 5W-40 compares?

Alright, well if M1 0W-30 is essentially the same as Syntec 5W-30 i wont get that. So probably either M1 0W-40, M1 EP 5W-30, or Syntec 5W-40. M1 come with M1 EP filter, Syntec comes with K&N. Looking to go 7500 miles on the oil, probably 10k with the M1 EP oil. Thoughts on these 3?

Oh, and my driving is mostly short trips in the city (35-50 mph), 15-20 minutes at most. Not stop and go traffic, just short mileage trips. I do some highway driving (55+ mph).

 

[football751]

Of that selection, the Mobil 1 European Car Formula 0W-40.

Thanks :cheers:

If I was to bother with it would it be worth ordering and using the M1 5W-40 over the M1 0W-40?

Sorry for all the questions, I've been running Syntec 5W-30 for a while now, and realizing it's not the best for my driving conditions I'd like to find what is. I know the best way would be to try a bunch of oils and get the samples sent off for testing, but I don't want to wait that long and I'm a poor college student :lol:

 

[football751]

Gah, it's all so complicated! Maybe that's why they us xW-40 in hot climates, doesn't take long for the engine to warm up cause it's so hot outside.

I would love to go with the Amsoil, but it's just too expensive for me.

I think I'm going to go M1 0W-40, as I feel like the 0W will give me the low viscosity at startup and on short trips that I need. Plus it meets the higher European standards like the Syntec 0W-30. I'll probably run the M1 0W-40 for 7500 miles, and hopefully then I'll have the money to send a sample off for analysis :cheers:

Also, looking at their spec sheets, Syntec 0W-30 has a viscocity of [email protected], versus M1 0W-40 of [email protected], so almost the same. At 100C the M1 is also a little more viscous than the Syntec (13.x vs 12.x) but not by too much. Plus jayman said his M1 0W-40 sheered down to a high 30 weight, so probably the same as the 0W-30.

 

[football751]

Is there a "severe usage" interval for the FJ that Toyota recommends for 07-09s? I know individual oils have their own recommendations (like Amsoil) but does Toyota recommend 5k miles no matter what your driving conditions are?

 

[football751]

jayman, any chance you could post up copies of your used oil analysis? Or links to the threads you posted them in before? Very interested in seeing them. And I never seem to have any luck with the search :lol:

Any particular reason you use the stock Toyota filter? I use whatever comes with the local oil change specials, which lately has been K&N and now Mobile 1 Extended Performance filters. Have also used a Bosch DistancePlus filter. Any reason to sue the stock Toyota filter over these? With the oil change specials I can get 6 qts of oil and one of the above filters for ~$40.
