Goop in the bottom of my Havoline Synthetic bottle.

[Audi Junkie]

Today, I was doing my oil service including ONE quart of Havoline Synth, 5w-30 SL. Looked into the bottom and there was about 1/4 spoonfull of amber goop in the bottom. I shook the bottle lightly before draining. I did not really check if the stuff was slick or sticky, now that I think about it. Kinda sucks, for a "100% synthetic base". ???

BTW- my blend was:
1q Havoline Synth 5w-30
1q Chevron Supreme 5w-30
1q Chevron Delo 15w-40
2.5q Havoline 10w-40 SM
1q Chevron Supreme 10w-40

It's pretty nice going down in visc from a 5w-40 HDEO, the engine is nice and revvy. Planning on 5000 miles.

i noticed the same when i used the chevron full syn. i am not sure what it was however the oil was 1 year old and the new bottle 1 month old did not have any in the bottom maybe the stuff settled?

Wow now that's a blend!

From what I've heard, nothing should settle out of motor oil these days, but maybe there is some special cases.

Nice blend, Audi. You deserve a brewmasters certificate for that one!

Does anyone else have a bottle of Havoline synthetic in their stash with this type of separation?

From what I've read, the high, 130+ VI index Grp III's tend to have solvency issues.

1/4 teaspoon is a minor amount, but it could be VI improver or friction modifier or pour point depressant.

Hopefully we can get Molakule or Bruce to comment!

I figure all the Chevron/Havoline products mix well, except the goop.

It's kind of a shed-clearing blend. All I have left now is Chevron Supreme and the Havoline Synth...and the Delo.

light colored amber gell is VII most likley.

brown thick oil is most likley Detergent/Dispersant.

Its the Auto-RX they are using in the add pack!


just kidding.....

 

[Blue99]

Yeah, Terry, goobers in the bottom of the bottle is a dead giveaway for Auto RX!

BTW, Thanks, Bruce, for your comments!

Thinking more about it oil storage out side at low temps for a long time ? months? may increase additive fallout.

This begs the question what happens in your car over cold days? While Additve fallout may occur in your car when then oil is new due to bad blending after a few days driving any undisolved polymer will melt and mix (kinda Like auto RX) in so older oil should never have a fallout problem due to undisolved additives.

Most additive fallout in new oil I think is due the oil not being blended at the right temp for the right amount of time.

This is most common problem is with VII since most are plastic and have bad solubility.
They have to be totaly melted into the base oil.

Example Raw OCP polymer needs to be mixed into the base for 10-12 hours at 250F and then has to be checked for "lumps".

Because of this only the "big" guys will form there own VII bases most small blenders like me will use a pre disolved VII it is a lot easier but more exspensive that is why the big guys will "Blend or melt" there VII in house.

I did a somwhat similar cocktail of Chevron SL lubes last week for my hi-mile 190E beater consisting of the ff:

1qt Havo Synthetic 5w30
2qt Chev Supreme 10w40
2qt Chev Delo 15w40

According to the visc calc it ended up as a 99.3 cSt 40*C/13.9 cSt 100*C..a 5-10w40 blend. Car now has a 2mpg improved mileage over the pure summer fill of Delo 15w40 w/c made the Benz a dawg..

Btw, I have one more Havo Syn 5w30 left(both free/for mixing next same cocktail)..neither had any of the "goop" settling.

I remember the days of running Mobil 1 5w50 year-round in my old watercooled VWs.

I guess that is too boring to to and wouldn't have anything to post on BITOG?

Here goes the 'blend' rant:
Really, what is with 'blending' already blended oil?

I've been known to dump a bunch of left-over single qts of various manf's into my least appreciated engine (usually an inlaws pro-bono oil change) just to get rid of the 'mis-matched' astard bottles, but if you want an oil to do 17 things, does mixing 17 oils achieve this end? Wouldn't it just be better to find one oil that does what you want it to do?

BTW AJ, the best thing you could do for your GT is to use Mobil 1 15w50 or ANY 15w40 summer, and ANY 5w40 in winter or year-round. Forget about hoarding gas, blending oil and simplify to enjoy life!

Audi Junkie; I have a few bottles of this same oil in my garage, about a year old. your post got me curious so I dumped two bottles into a clean container and checked the bottles thru the opening...some discolored leftover stuck to the bottom, but not enough to call it 'goop'. in your case it might have been VII dropping out.
p.s. my Audi 1.8 seems to like 5W30 just fine, altho I'm probably in the minority of 1.8 owners.

I only blend within brands. If someone can look at VOAs from different brands and determine a similar additive package, go ahead and blend that stuff together. IMO, it seems various adds and basestocks work together, and Chevron has all their oils within a certian base oil system. Hey, I HAVE the Havoline Synth, with a somewhat weak add pack, and don't mind buying the Delo to beef it up. I also bought out the Chevron Supreme at W*M, alone it would be fine, but why not a q of Delo and a q of Havoline Synth to "nicen" it? Blending for visc seems to be totally resonable, say for winter 1/3 10w-40 plus 2/3 5w-30 and the opposite for summer. Sometimes I think 30 weights are so thin BECAUSE you are supposed to blend them. I always did so before coming to BitOG, why not now?
