Oil question?

Hopefully nothing damaging or irreversible. This is the reason for this post.

 

I think the other guys' nailed it:

Truck runs great, noticing a whin or growling noise on start up until it's warm lately. I'll try a different brand and report back on my findings. I feel better after reading your replies.

 

Cool thanks. I haven't discovered the search function on this phone apparently.

 

Dude you are drinking the Amsoil Koolaid.

That "white Goo" is not the oil breaking down. It is moisture mixed into the oil vapors at the top of the extended filler neck. The extended filler neck doesn't get warm enough on short trips to eliminate the water vapor in this area. It is localized in the filler neck and is not an issue.

What is an issue is people that do not have a clue talking crap on a message board. Amsoil is good oil, but it is not manna from heaven. Mobile 1 is just as good, as far as that goes so is Dino oil as long as it is changed regularly.

 

I run moble 1 exclusively and get the same peanut butter every winter due to a 10 minute commute.

 

Ffs everyone....it's MOBIL! There's no E on the end! Damnit!

 

No the kind with the E on the end is the kind that foams up.

 

Lol

 

The milky white color indicates two potential bad things that may have happened. Either your oil formed an oil/water emulsion or there is bacterial formation.

Ordinarily oil and water do not mix however since car engine oils have detergent/dispersant additives which are hydrophillic (water attracting) which holds water and condensation. As water levels rise, the stirring action of your oil pump allows the oil water mixture to emulsify giving a white color. You probably have allowed the car to sit for a long period. For some reason bacteria can grow inside your engine (because of long storage or being idle for weeks/months), this is also bad. Certain bacteria thrives on sulfur which is also present in your oil. This is another reason for the oil's changing in color.

Foaming is not caused by detergents as some people mistakenly said here. Typically foam is indication of contamination (water or moisture in your case) but could also be caused by the presence of ther chemistries that upset performance of anti-foam additives, normally silicone-based or acrylates present in an engine oil package. Defoamers allow easier break out of air molecules to the oil surface.

Regardless, when you see a milky white color, it means the oil is degraded so just go to your mechanic and get a new oil change.

 

Dude don't switch to Amsoil just for this bit. The little bit of "pudding" you have at the top of the filler neck is caused by the extended filler neck and plastic. It doesn't get heated up fully on a short trip. Mobile 1 is a perfectly fine oil and it is Not Breaking down.

Switch if you must, but do a little more research first before wasting money on Snakeoil oops I meant Amsoil.

 

The pudding goo in the engine may be common but I wouldn't agree it's nothing to worry about. The goo is formed when the unsaturated hydrogen bonds in the oil form acids and the oil is breaking down and needs to be changed. I bought my Tacoma used, the oil had been changed by the dealer and there was no goo in the cap. If you have goo in your engine and switch to 100% synthetic it will clean out the goo and may clog the filter sooner than expected.

 

Mobil 1 is made with a proprietary blend of high performance synthetic basestocks fortified with a precisely balanced component system. Mobil 1 meets the ILSAC GF-5 performance standards.

 

I've been using mobile1 full syn since 2004ish in multiple vehicles. Have never seen the white goo. Its not the oil.

 

Had this the first oil change I performed on mine (saw it and it scared the crap out of me... TW eased my mind). Since then I have used Amsoil once and Mobil 1 the rest of the oil changes (5). I've only had it show up one time since then and it was very little and during a cold winter (w/ a short commute). Amsoil makes good oil, but you are going to pay an arm and a leg for it (assuming you want the good FS stuff). Mobil 1 FS is very popular on here. Do a little searching on TW before you jump into Amsoil.

 

Used mobil 1 full synth. on my 1992 Toyota Pickup, I use mobil 1 on my 2006 Tacoma 4.0. That's 24 years in the making and I haven't once had an engine failure.

Mobil 1 is a higher tier oil manufacturer, with no known product deficiencies.

Amsoil is like Royal Purple--Brandname. Performance circles like NASCAR, Supercross/Motorcross, and Baja use it, so when you buy Amsoil, you are paying not only for the oil but also all the promotion it gets in competitive sports who can afford to buy it. Heck, even Motor Trend promotes it. It's brandname advertising.

Drive your truck, change the oil at regular change intervals, and clean your oil fill neck. Keep in mind, this problem is limited to the oil fill neck. Clearly you live in a cold environment, which is to blame, not the oil.

 

Just noticed, my phone corrects to Mobil with an E.

 

Yeah it sits most of the week while I'm gone. When I do drive it, it's to the store and gym then back to work. Maybe a thirty minute round trip.

 

There is fully synthetic oil it is used in turbine and jet engines we used a few brands in the Air Force I remember one had a stylized concord airliner on the can. Of course that stuff would be way too light for piston engine.

I would assume they do make full synthetic for piston engines though surely it is fairly expensive. The turbine oil was very expensive they kept it in the supply house and you had to order it while the normal oils for the diesels they stored in huge bins so you could walk up and fill a can.

Someone goofed once and topped a turbine with normal oil luckily they realized and didnt run the thing... FNG.

 

The guy who started AmsOil was a jet fighter pilot, he decided to make 100% synthetic oil for road vehicles. Jet engines must use 100% synthetic oil due to high temperatures.
Jet engine oil does not have the additives piston engine oil needs, the oil in jet engines doesn't come into contact with combustion products like the oil in piston engines.
