Looking through all the documentation for our new RAV and noticed that the oil Change interval is noted at once a year...that seems odd to me. On our OB the interval is every 8,000km. I put a fumoto valve on the OB and change it myself every 6,000km. I think that I am going to put a Fumoto valve in the RAV and change the oil every 6-8k km.

Thanks for the link. I am going to stick with a regular interval of much less than than what they suggest. Just makes sense to me....and having a fumoto. Alive makes it so easy...

In the US we have Toyota Care (2 years service free), so it makes sense to go with the synthetic which is included, at least for the first two oil changes.

As automotive and lubricant technology improves, this has become quite the contentious topic.

Some, based on feelings or old practices, will change their oil early. Others, based on empirical evidence, stick with 10,000 miles oil changes.

My multiple used oil analyses show that the oil and filter work quite well to 10,000 miles.

my honda maintenance minder gives me a 6500-7500 notice of 15% life left. I do 7500 now and that and will likely do it for the RAV as well. The RAV gets alot less usage though... 23k in 33 months, accord has 58k in 26 months...
10,000 is probably a legit interval, but it's hard to change two decades of ingrained behaviour....7500 will have to do...

Maintain the car according to the specifications to keep the warranty. If you want to change it earlier than specified to feel good, do so. If you really want to know what is going on in the engine, start getting your used oil analyzed at a place like Blackstone labs. Everything else is just speculation.

X2! A lot of variables impact oil life. Do a used oil analysis at 8k and the results will tell you how much life if any is left in the oil. UOAs are cheap for what they provide. Also, post the results over on Bob Is The Oil Guy | The Internet's Number One Motor Oil Site

Tremendous amount of knowledgeable folks on this site.

Sorry guys ... I'll never wait until 10k miles to change the oil. I don't care what analysis is given. It costs me $40 to change fully synthetic. I have no problem shelling out an extra $40 a year to make sure there's clean oil in there. 5K mile oil changes on fully synthetic is not an issue. It's far cheaper than risking catastrophic breakdown.

Same for me. Never used a oil analysis - instead pay $27 per oil change using OEM oil filters & M1 full syn oil. Cheap insurance for me and I know the oil & filter is good. Just can't see a oil filter lasting upwards of 10k and still filtering as needed. So it's been 5k for me. Just do what works for you.

5K oil changes are not an issue? How do you support that claim while simultaneously claiming that 10K oil changes are hazardous? Are your statements based on facts or feelings?

I'm not trying to fight. Honestly. I'm just genuinely curious how you can so comfortably claim one thing (5K) is o.k. while another (10K) is not o.k...all the while admitting that you don't really care what the science (the analyses) says.

It'll take time for feelings and old practices to catch up with science. Twenty years ago, I couldn't fathom switch from 3,000 mile oil changes to 5,000 mile oil changes. Ten years ago, I couldn't imagine switching from 5,000 mile oil changes to 7,500 mile oil changes. Three years ago, I couldn't imagine switching from 7,500 mile oil changes to 10,000 mile oil changes...until science showed me I had nothing to worry about. Just like previous increases in oil change intervals, eventually we'll wonder what all the fuss was about.

Down the road repairs on various higher interval'd vehicles have shown me that there is plenty of issues to worry about, usually caused by misengineering and budget snafus. Science? would that be CAFE MPG, or lower cost of ownership marketing(great for the lease zombies), or the eco-greenie govt to manufacturer tax discounts for lifetime or extended fluid intervals? Science... doesn't mention the number of worn timing chain and tensioners, failed VVT components, sticking or broken rings, oil consumption, bearing wear, rod knock, start up rattle, piston knock,.... which are all pretty common at the used car auctions where many dealers dump your trade-ins.

Toyota doesn't give all a blind 10k/yearly interval. Many fall under Toyota's 5k/6month severe service interval. Too bad dealers and owners are too clueless to even know that a severe service interval exists. Read your maintenance manual.

Severe service 5k/6mo interval:
Extensive idling or low speed driving... who here has a remote starter? or enjoys the city/highway traffic with their commute? or likes to run the A/C or heat while the prettier half runs into the department store or supermarket?
Repeated trips <5 miles when <32F? Anyone in northern half of country with winters?
Towing, car top carrier, or heavy vehicle loading? I'd consider the kids, their sports/hunting/fishing/hobby gear, along with the wife as 'heavy loading'. But, didn't see Toyota's definition of 'heavy loading'. Carpool?
Dirt or dusty roads? unpaved roads, salt/sand on snow/ice roads, desert or wasteland roads....

Toyota is a great automaker. Too bad they can't come out with an oil life monitor algorithm. Fixed mileage/time intervals for all are such a primitive science. I guess that an actual oil life monitor algorithm is just an overly advanced science for Toyota to digest.

Concerning UOA's.... good data requires trending. Bad data means you're simply too late for the interval. Borderline useless to try to extend the $40 oil change a few weeks with a $40 UOA. But, having the data, that most can decipher, sure is hipster beard/tattoo/piercings cool at theoildrop forum.

Nothin' like a good oil fight, eh Greasy? :wink

If one decides that a 10,000 mile oil change is bad, what empirical evidence is that based upon? UOAs? Carefully tracked vehicle failures?

If one decides that a 5,000 mile oil change is good, what empirical evidence is that based upon? A UOA? Gut feeling? Unfounded knowledge about oil? Old wives tales? Anecdotal observation that 5K oil changes are commonplace and vehicles seem to last just fine?

If a 5,000 mile oil change is good, why not change it at 2,500 miles to get even more life out of the motor? After all, why should we trust manufacturers when they tell us to change our oil every 5,000 miles?

Point is that oil discussions are a big swirl of emotions, fact-less opinions, and anecdotes. Even when presented with facts, many will simply say "Well, I don't believe that. There's no way oil can do that." Even when you show them that it can, they still don't believe it.

It's o.k. Just like the switch from 3K to 5K to 7.5K oil change intervals, sooner or later we'll embrace the new lubricant and manufacturing technologies and we'll look back on these 10K oil change debates as silliness.

That's so funny. Why would I pay for an oil analysis when I can just change the oil for $40? Feel free to keep the old oil in there as long as you want. It's your car.

5000 miles is a good number for me, regardless of your ranting. I want new oil in there. Life is simple ... new oil is better than old oil.

You just need to do the analysis once to see what's appropriate for your driving conditions.

I first encountered the 10,000 mile oil change interval in my 2002 Acura RSX. And the nutty thing about that? It only required a filter change every other oil change, so at 20k! I did follow the 10k interval, just I did the filter as well.

Took my Celica to 200,000 problem free miles on that long of an interval too using Mobil 1.

It's not a rant, but if you feel it's devolving into an emotional argument rather than a factual discussion, just holler and we'll quit.

Why pay for oil analysis? Well, you may not have to pay for a UOA. There are plenty out there already (and increasing in quantity as 10K oil changes become more regular). If one doesn't trust existing UOAs within a particular category, then accomplishing one's own UOAs could potentially cut your lifetime oil change costs in half. That was my primary driver for getting proof with UOAs. I did 4 at a cost of $140 ($35x4). Plus, there's a gee whiz factor of seeing what's going on inside my motor and setting a baseline for future troubleshooting, if necessary. If I drive the vehicle to 250,000 miles with 5K OCIs, I'd spend $1750 on oil changes (50x$35). At 10K OCIs, I spend $1015 (25*$35+$140).

You say that 5K changes are fine. Why are they fine? Upon what do you base that confidence? Why wouldn't a 2,500 mile oil change be better? Understand that's not fightin' words or a challenge. I'm genuinely interested in what you base your decision on. Whatever criteria you use to reassure yourself with a 5K oil change, would you at some point be willing to apply that same criteria to 10K oil changes?

There is currently a $12 rebate on Mobile one oil....
So.. $13 for the oil...

Wow, I'd save $735 over 250K miles with 10K mile oil changes compared to 5K mile oil changes?

You know ... a new engine is about $5000.

I'll spend the $735 happily and readily. Not a problemo at all. :nerd
