Do you think I should switch to fancy oils like Amsoil Singature Series and Pennzoil Uk
Ultra Platinum? I am pretty religious when it comes to oil changes. I changed the oil every 5 weeks and 5,000 miles

no signature 0w-16 yet, only OE. I am an amsoil reseller, otherwise I would be using signature already. I dunno if they are going to be doing the 0-16 in their signature formula. The pensoil ultraplatinum is good oil, and if the price is reasonable, why not? my engine has been running Amsoil OE 0w-16 since 19900 miles, since the dealer could not get me in for my second free oil change, and I wasn't waiting. the 40k oil change was sampled and sample looked great, with expected stuff. if you do a lot of short trips, or the engine is doing the on/off thing a lot, change your oil sooner than 10k. fuel dilution is the only real issue they found, so if that continues, it might be worth changing earlier to avoid issues related to it.

Like I said before, I change my oil every 5 weeks and 5,000 MI. Also I just checked, Pennzoil Ultra Platinum is not available for 0w16

I also need to stop being cheap and boring, drive this thing in sports mode on the highway once in awhile. I have a very very light foot

again, gasoline is a strong solvent, and the stuff in those little bottles is not gonna make it stronger, nor will it dissolve anything that the gasoline would not already dissolve. Gasoline was originally used as a solvent and was a byproduct of making diesel fuel and heavier fuels. In fact, it was also used as Lamp/lander fuel before it was used in cars, and was sold as "whte gas". Its also called coleman lantern fuel. there is nothing you can add to gasoline that will dissolve anything more.

I recall that the gasoline was a byproduct of making kerosene rather than diesel fuel, as in the times (mid-1800's) there were no diesel engines. But the differentiation between petroleum fractions is kind of smudgy, so the 1800's kerosene may have been a "everything that doesn't evaporate immediately and it colorless and not too viscous", kind of like a mixture of gasoline, kerosene, and diesel fuel in accordance to today's classification.

Fuel System Cleaners - Fact Or Fiction

We’ve tested a bunch of pour-in fuel additives in Fact or Fiction over the years. Can you really blame us? With all their promises of horsepower and torque incr

www.motortrend.com

They don't work like they claim, and would need to be so strong in order to function as described that they would harm you car's emissions systems badly. and they legally cannot be sold that strong due to environmental regulations, and the fact that they would likely dissolve the plastic bottle they are in. Even seafoam, which is good stuff, is more or less just another gimmick that really doesn't do much in the concentration that its sold in(this is also why you need to "hot soak" your engine with it for it to actually work properly).

secondly, in the new siennas case, its both DI, and PI. The port injectors will keep the valve top's from getting carboned up, so you should really never need an induction cleaning service at all, and if the DI injectors are "clogging", it means that there is poor combustion happening, which would have a root cause that you would want to figure out, but the main reason for poor combustion is usually crappy gas, and at that point, because of the way the injectors work, you cannot clean them without fully disassembling them and putting them in an ultrasonic cleaner. if it can't push it out the holes, its not gonna come out no matter what you throw in there. those little bottles of "mechanic in a can" shit have been mostly snakeoil for decades. its an easy upsell for a shop to charge you $50 for an "injector cleaning" when all they do is dump a bottle of mystery fluid in your gas that cost them $3, and that is basically like a drop of piss in the ocean in concentration in your gas, which is already a very strong solvent.

gasoline is actually a very mild solvent, compared to some of the fuel system cleaners that actually work. That's WHY they work. And I am talking very few "snake oils". Techron, B-12, and BK44 are amazing products.

If you are denying the FACTUAL cleaning evidence of Chevron Techron, you need to be more open minded. I know it fixes issues, because I have seen it work in person. Obviously I am not going to change your mind, so carry on =)

Car Care Nut on YouTube says that we don't need these fuel cleaners. Says just drive your car as if you stole it on the highway, and it should burn off everything

yes, revving the motor high every once and a while is a good thing.

I disagree with the fuel cleaner statement, because todays fuel is 10% ethanol, and basically shit fuel. Back in the day the fuel filters were replaceable. Now they are not replaceable. That's why it's important to use QUALITY fuel, and occasionally use chevron techron.

I buy Arco gas and it is Top Tier. It is cheaper than Chevron but it does have Top Tier additives

That was the exact video I stopped watching and trusting Scotty Kilmer. That video seemed way to good to be true, and at the time it came out the comments were filled with people explaining how it was a fake, how it wasn’t even the same cylinder pictured in the before and after.

Here is a video that doesn’t look like someone taking a bunch of advertising money. Result?Cleans some soft carbon, a tiny bit of hard carbon. Most importantly, the results are NOTHING like what Scotty Kilmer “shows”.

Techron appears to work better, but again, it’s not a miracle worker.

So, yes. They do work, at least to some extent. But not to what Scotty would have us believe, or even the claims on their own bottles.

Personally, I’m just gonna keep doing what I’ve done. Buy whatever gas is cheapest or most convenient to get, which around here is usually Kwik Trip. If I’m not going through the gas quickly, like for a motorcycle stored over winter, I’ll get ethanol free, whatever brand, and use some Stabil. For stuff like two-stroke for a trimmer, I would use only ethanol free gas alone with Stabil. And I won’t worry about a bit of carbon in the pistons.

2% dilution is very low and not high enough to be worried about. 6% is the threshold that further troubleshooting is done. Anything over 8-10% should be an immediate oil change, and not running the engine until changed (and the cause found and fixed)
The most imporant aspect to oil sampling is monitoring all data over time.

 

[jseyfert3]

For my 2013 Honda Pilot, for which I have attached my oil report, I had 1.5% fuel my first test and 0.5% for the two subsequent tests.

The first test was in February while the next one was in June and third one in September. I would hazard a guess that I had higher fuel in the oil on the sample I took in February as the cold weather meant more fuel rich starts and cold engine cylinders condensing fuel which slides down the cylinders into the oil. Whereas in the summer engine aren’t as cold to start, warm up way quicker, and stay hotter longer. Probably helps we towed a camper a lot too. Long trips at high temps evaporating gas back out of the oil most likely.

I wouldn’t be surprised to see the fuel % drop after the weather warms up.

Also note that your viscosity is still within range. As I currently understand, besides additives the viscosity is the most important aspect of the oil, and clearly the 2% fuel has not diluted it to the point the viscosity has fallen out of spec.

Great point. Yes my oil went through sub zero temperatures as we had snow storm. And lots of short trips.

Way off topic but on a motorcycle forum I’m on, several members had had a failure of both the vacuum operated fuel petcock sticking open and one or more sticky float valves in the carbs. This combination means the entire gas tank will drain into the crankcase. Or at least as much as will physically fit into the crankcase. Gas in oil? No, how about some oil in your gas!

Got me thinking if need to get oil checked as went two months between fill ups... end of Nov to end of Jan.

Majority of trips are close to one hour and at least 30 minutes highway.

 

[cougarhound]

I was just doing 90mph for a while on the highway to clear it out. I do this a few times a month. Sometimes I also drive in 3rd gear in the highway for a little bit. I haven't figured out how to do this with the Sienna yet though.

I run 10,000 miles oil changes on my little Prius C and I have no oil consumption issues at 140,000 miles. I often rev the crap out of that thing to make up for the weak output. I started doing the "Italian tune up" after I had some catalytic converter issues on my 4runner and I think it cleared it out.

I also learned to drive in a Mazda RX-7 so I believe revving is good for the car. lol.

FYI, the Amsoil Signature is not API certified, which may cause warranty issues (which is rare, never heard of it) but I'm pretty sure you almost out of warranty anyways at 90k.
Amsoil SS is pricey thought for 5k changes, mobile1EP or Pennzoil UP would be my second choice.

I'm currently using 0w20 Mobile1 Extended Performance at 2k miles.(500 mile breakin oil change). I will get a oil analysis at 5k.
Also have a case of Amsoil Signature 0w30 that may start to use at 5k and beyond.

Easy to do in the Sienna. Bump the shifter over into manual mode and select 3rd "gear." Gear being simulated since it's a CVT, but it'll hold very well and will just rev more and more as speed increases. Without a tach tho, I wouldn't go too extreme.

I know this, but I can't possibly justify the cost. Would love the better headlights, better infotainment, and most importantly better quality seating material. But that price range is in nicely equipped new Volvo XC90 T6 territory, and certified XC90 T8 (plug in hybrid) territory, a competition that this van could never win IMO.

FWIW, an OBD2 reader paired with free app can be useful to monitor RPMs. Some OBD2s go for 10-15 bucks.
