Switching to synthetic, hoping to do it twice a year

Showing me ClipArt is not compelling enough. UOAs with data though, are. Unless you have sources.

 

You're right. I think it's clear no one in this thread is nearly qualified to share a real data-driven academic research publication on how synthetic is better than conventional for a 1st gen tacoma.
But it just seems like companies put a lot of money in R&D into these areas - it would make sense there are higher quality oils out there with better properties.
And coming from my limited 6 years of being a process engineer, my first hand experience in process control gives me enough confidence to opt a synthetic oil over a conventional oil and that's good enough for me

 

Oh yeah, I don't mean to sound like I'm doubting there are various qualities of oils out there. I'm certain that's true.

Marketing sells. Pure and simple. Every industry from pharmaceuticals to cars, to oils/additives. The pharm industry is especially bad about it. They will make some minor change to an inactive ingredient just so they can renew the copyright on it, then market it like it's some new and improved formula. I have no doubts companies like Chevron, Penzoil, etc do that too. I bet they've had the same basic formula for decades. But every year we see commercials about their "new and improved" formula that performs "better" (but better than what?).

 

yeah I hear you - I'm sure there's tons of that going on too. marketing does sell
But they do use ISO standardized tests to show this - How do you communicate standardized testing results to a general public?
That said these tests are sometimes easily 'smudged' or 'subjective' in individual user method anyways. (though the goal is obviously to eliminate this)

 

Color doesn't meen anything. You can post all the dumb clip art you want. - Your post has very little substance and doesnt explain anything.

 

Dont you remember back when Castrol GTX came out with the Sludge fighters "Sludge slows you down" campaign.... Or the Magntec Nano Molecules which cling better to metal marketing ploy.

 

Magneto Nano molecules. It's science. Just like magnets on your oil filters.

 

Posted the clip art so you could try to understand. In simple shapes like circles and rectangles. Just for you.

Here maybe this will help you comprehend

 

Oh god, I had forgotten about that, lol

 

I don't give a hoot if synthetic is better and what it costs. In my Tacoma I'm running dino oil since the day one, change it every 3k miles and the there is zero "sludge" in my engine (I know, because I've seen what is under valve cover https://www.tacomaworld.com/threads/valve-cover-replacement.587686/page-2#post-19641555). The engine has 320k miles now and burns zero oil. Dip stick shows the same color and the same level just before oil change as it was just after the oil change.

On the other hand my 2012 4Runner came with synthetic oil and that's what I'm changing to every 5k miles. By the way this is what my local Toyota recommends: dino for old Tacoma, synthetic for new 4Runner.

By the way if your oil is black and your truck is not diesel, the problem is in the engine, not the oil.

 

Oil and tire debates are the best.

 

And LBJ too.

 

I couldn't agree more with this comment. The amount of advertising directed at consumers who have zero backgrounds in pharmaceuticals. After seeing the never-ending commercials, the drug industry hopes they will motivate people to ask their doctor to prescribe drugs seen on TV. All driven by money and selling product.

 

Mobil 1 is the best oil!

 

Here is my take on this debate for whatever the hell it is worth. Many Tacoma members have already provided some excellent insight on this thread. Changing oil and filters at regular intervals is an excellent way to keep any engine running.

Synthetic oils are developed as we all know in a laboratory. The chemical engineers responsible for their development are looking for the best properties to lubricate an internal combustion engine as well as keep it running. Synthetic oils have become a very mainstream item in the last twenty years. They are, by far, the superior lubricant compared to dyno oils, and this is because they were developed in a laboratory.

One thing you can do when switching to synthetic motor oil is that you can double your oil and oil filter change intervals. Synthetics are slicker than dyno oil so, as a result, you will notice that your engine will use a little more oil between oil changes than dyno oils. This is because synthetics can pass piston rings and valve stems much easier than dyno oil. For example, we switched our old Tacoma, which is a 3.4, to Castrol 5W-30 full synthetic before it turned 100,000 miles, and it never used a drop of oil between oil changes. Now it uses about a 1/2 quart of oil every 3,000 miles, and it has done this consistently since we made the change, and our Tacoma now has 176,000 miles on it. We change the oil on our Tacoma any where between 6,000 to 7,000 miles, and we add a 1/2 quart of oil to the engine anywhere between 3,000 and 3,500 miles.

Because synthetic have become so popular, dyno oil has also received a lot of research and development in the last twenty years. Dyno oils are far better than they were 40 years ago. They have benefited from the popularity of synthetics. As what has already been pointed out, synthetics are marketed by corporate America as the greatest thing since the wheel, and they will continue to be marketed in this fashion.

Hope that helps,
Paul

 

changing mine since 2006 corrolla and since 2009 with my taco once a year amsoil signature series with eao filter for life boi

 

Not true. I am using Signature and I'm paying $9.65 a quart. I have been on their website. I just ordered 6 quarts of it.

 

No, you don't have to waste the time and money with oil samples but is doesn't hurt to know if you have a head gasket leak, whether or not the engine is running rich, have fuel dilution or whether you have a small leak somewhere in the intake system letting dirt in. Anyone can read an oil sample with a little learning. Blackstone actually has a page on their website that explains what means what. It's not hard. For example, high aluminum numbers can mean you're pistons are being worn away due to a dirty air filter or a leak in the intake system you don't know is there.

 

Penzoil Platinum is 100% synthetic. It's just for marketing puroposes but it "is" 100% synthetic.

You really are an argumentative A'Hole, aren't you? By the way, I've been using Fluid Film for years and who would want to go to Disneyland in this day and age. The one in California comes to mind. You probably need a map to get through the minefield of dung piles and heroin needles like the hotels give out in San Fransicko. And don't forget the satchel full of spare change for the street urchins. I road the Matterhorn 21 times in a row on one trip there 30+ years ago. Been there, done that. Here it is a second time, numb-nuts:



You might also try actually reading what I said in one of my first posts. What's wrong? Is your reading comprehension lacking? Or do you just not understand english? Marketing never had anything to do with why I run Amsoil. I saw the results of it back in the 90's and I've done a lot of reading about oils over the years just out of curiosity. I also said I use it in this particular vehicle for the reasons I stated in my post. You might have missed that as well just like you probably missed the fact that I ran Mobil 1 for 15 years in one car as well as Panzoil Dino. I've run a lot of oils in various cars over the years for different reasons.

No, I don't frame the reports. They get thrown away after I read them. Every report has all of the previous reports as well. I probably should post them the next time I do the change at 10,000 miles. You might actually learn something.

As for my "cold day saga". Try cold "months". You probably missed my point on the temps where I live. Maybe everyone that lives where it is even colder, like North Dakota should run right out and start buying Dino again. Have a brain fart or something? Or was it your lack of reading comprehension again. Also, if you read my posts I never "recommended" anything. I guess you missed that as well.

I suspect the cab companies in Las Vegas and Phoenix, AZ will quit using synthetic and follow "your" advice if you were to share your vast knowledge on how to save money on oil changes with them. Synthetic is just a waste of money in 100+ degree heat and stop and go driving. We all know that. Some of them even use ........Amsoil. The various police departments around the country will want to hear your opinions also. I'm sure. So will the various municipalities nationwide who use synthetic. Clearly they are just "fanboys" for whatever oil they use. I doesn't have anything to do with the fact that it saves them money in the long run. The fact that synthetics have better add-packs, keep the engine cleaner for longer, resist burn off and maintain viscosity better couldn't possibly have any bearing on that, could it?

Incidentally, synthetics and especially Group IV's and esters are more purified with less contaminants which is another reason they last longer. They also have a more consistent molecular structure. Silly me, I brainiac like you would already know that. Group IV's and V's clean better and esters handle pressure better. Redline is higher in Esters while Amsoil is higher in Group IV's or V's. But you knew that as well, I'm sure.

Why, I'd bet if I sent your posts to General Motors and every other huge auto manufacturer around the world they will certainly see that you are wise beyond your years, clearly understand oil technology better than their engineers or any tribologist for that matter and, without haste, immediately cancel all synthetic orders and switch over to Wal-Mart Supertech for factory fill. It's cheaper 'ya know. Maybe you can call up Lockheed/Martin and Boeing as well. No doubt they've been using the wrong oil since the 70's when Amsoil invented the first synthetic oil for jet engines. One call from you and I'm sure they will see the error of their ways. It might have been the 60's. Who cares?

Crisco was used as a diesel engine lube at one time. Maybe they should have stuck with that. It was probably cheaper. Heart disease started in this country when they decided to market artery clogging "diesel engine lube" vegetable oils for cooking. Yep, Olive oil and coconut oil are far more expensive but that's what I use most of the time. Maybe I'd better go back to Wesson or Corn oil. It's cheaper.

 

I'll actually fight that OEM LBJ failure fight but I've had one fail so I have a reason. Haha.
