Can I Use Syn Oil With An Engine Over 68k Miles?

Everyone knows what claims are reasonable and not. He might have also misposted, exaggerated slightly and tried to play it off or something, or maybe he forgot about other things done at the same time that had an effect, let's all try and be cool.

I know it's a bit off topic but since it was mentioned . . . .

I will say that running 40PSI in an attempt for better fuel economy is unsafe and not worthwhile. Running higher PSI is overrated. I've tried running 38PSI and it made absolutely no difference from running 35PSI. I've found that once you get past about 33-34PSI it makes pretty much absolutely no difference in MPG and mostly a belief.

The major and most important difference is 34-35PSI maximum will give you better traction for hard manuvering and hard braking, especially at higher speeds or in the rain. If the tires used don't have really good traction, it's best to take it down to about 33PSI maximum. I strongly beleive that running too much pressure is also a major contributor to accidents where people can't stop in time or manuver correctly. Even with ABS running too much pressure still can lengthen stopping distances significantly.

Unfortunately, it is a common practice. Many tire shops and individuals overinflate tires thinking it's going to improve MPG, handling and often do it inadverdently using an inaccurate gauge or not setting pressure when cold and after not being driven. People also often go by what the tire's sidewall says not realizing it's "maximum possible pressure under maximum load the tire is designed to handle", not an actual recommendation like the placard on the vehicle.

That "Allen" guy shouldn't be handing out any advice on oil. Instead, he should stick to something else that he might know, but based on his horrific oil advice, I'm not sure that he knows anything.

Note to U.S. auto makers: Don't spend billions researching ways to achieve the latest CAFE standards (mandated fuel economy) Just by Tufoil, and all your problems are gone!

My combination of oil/additive/air filter/fuel injector cleaner has worked extremely well for the last 8 years with nothing but success for seven cars. I have not exxagerated anything. I just wish I had taken a photo of the LCD when it was reading 18.3 and then 27 MPG. Its down to 24.8 since I removed the K&N air filter and replaced with a paper element.

Would you guys believe me if I had a photo of the LCD reading 27 MPG? Perhaps I should reinstall the K&N and take another trip just to prove it?

It's funny that people will argue with success. Even with proof, you guys would probably still call me a know-nothing idiot.

It may have happened but how do you know it was the tuffoil alone? Sounds to me like moreso a combination of other things or a miraculous coincidence. I think if anything the Amsoil Synthetic might be a big contributor or switching over to a viscosity more appropriate for your driving or climate.

Come on, PLEASE DO NOT CONTINUE TO ADVOCATE ADDITIVES

Volvo recommends AGAINST USING ANY ADDITIVES and for good reason . . . .

Only acceptable additive in my opinion, is for an engine flush such as Valvoline's Pyroil Engine Flush or Marvel Mystery Oil right before an oil change.

Other than that, use synthetic. If the engine has a problem, consumes oil, simply bump up the viscosity a bit depending on climate and if using synthetic or not.

Additives that are Teflone PTFE or even based are also known to kill turbos, not good.

hey 850 T-5 that mystery oil how do you use that? you said run it for a while before oil changes? how long? what about fuel addictives like lucas or mystery oil as well?

Yes but it has NO PTFE or Teflon. It's completely different and NOTHING LIKE any garbage additives. It's a widely used, trusted and proven crankcase and fuel injection cleaner.

Sure it's an additive in respect to you "add it" but it's not a typical additive.

It is NOT used with the claim or belief that it renews engine internals, adds any type of special coating to cylinder walls or anything like that. It cleans engine internals, cleans and lubricates fuel injectors.

MMO has been around since the 30's, has been a proven crankcase and fuel injection cleaner not only in the aviation industry but automotive industry and one of the most trusted crankcase and fuel injection cleaners available.

Usage as asked -

Marvel Mystery Oil (MMO) can be used as a Fuel Injection Cleaner "or" added to Engine Oil to help keep the crankcase clean.

I typically add a bit of Marvel Mystery Oil (a little more than half a quart) to the engine oil and rest to the fuel every so often in all of my Volvos. I would maybe use it for a couple days up to a week before an oil change. This is more just to help keep the crankcase clean.

If you are in need of a fuel injection treatment. It's best to do about 3-4 MMO treatments. Basically right before a fillup just add about an OZ or two more than recommended on the bottle then fill up so it mixes well in the tank.

Hey FredMC,

I just wanted to say thanx for introducing me to BITOG. Great site. I wish I'd known about it years ago.

So far, I've been treated very well by the regulars. Nice people.

Yes I see that, they do have class. Just don't be making any wild unsubstantiated statments and you will do just fine there. They really don't subscribe to the Pennzoil basing, or claims of 8 MPG increases with an oil change and additives. You will learn quite a bit about the truths, not myths of oils and additives. Some did call you crazy, some handled it better than others. Seems like that will give you something to do,, ha.

I wouldn't swear at them though, I considered the source but I wouldn't do that on here again. Moderators may just ban you.
