Synthetic oil

Ive heard that in Germany Mobile 1 isn't considered a synthetic because it doesnt meet their heat dissipation standards. Anyone know if theres any truth to that?? i know their leading synthetic brand out there is Pentosin or something like that but ive never asked anyone else about this.

 

yes Mobil 1 is a group 3 oil, they did change the formula and it's not as good as it used to be, thank Exxon for that it's been 4-5 years...
you can research more about differences in group 3 and group 4 oils ;p

 

and you really believe that? it's called marketing lol
when you do have a problem with the engine they'll just blame it on something else, the cost for you to prove it was their oil's fault will be greater than a brand new engine lol

 

You could too...no one makes a gp IV-only oil because it won't dissolve additives. And gp V oils are prohibitively expensive-- you can find them if you want though. Your A/C compressor probably uses about 4 oz. of it. So everyone uses gp III and gp III+ in their blends, even Amsoil.

GP III+ is effectively as good as GP IV now so it really makes no difference in use. So saying it's 'not as good as it used to be' is truly misleading. If anything, it's BETTER than it used to be, if your looking at 5 year old information! In other words: you're spreading old myths.

Finally, GP III+ is getting better all the time, as are mineral oils. So it's quite true that EVERYBODY is better than they used to be!

 

Germany, as most of the EU, has a strict definition of 'synthetic'. But they don't market or select oils based on marketing terms like we are forced to in the US anyway. They use ACEA specifications which grades oils based on use characteristics to meet drain interval and strict government mandated emissions standards. It doesn't matter if it's GP IV/V (all synthetic base stocks) or or GP III/III+ (petroleum base stocks), if it meets the ACEA spec for grade that's all that matters. In truth, they are a lot smarter than the US and don't let 'synthetic' marketing hype interfere.

Mobil1 sells some oils certified to ACEA specs (look at their 5w40 Euro formulation) but as Europe isn't their market they don't worry about it. To sell in Europe effectively you have to formulate and certify an entire product line to meet ACEA specs. I think the only reason they bothered with that is because it's also VW 502 certified, required to maintain warranty in late model VW and Audi vehicles in the US.

 

I use Mobile 1 as it is close and one of the cheaper synth in my area, and lots of people use it and I havent heard anything bad yet.

Now I read in my owner manual that full snyth 0w-20 is what i should use in my 09 4cyl taco?? I have been using 5w-30 but want to switch for better winter starting. Do i need to flush my taco oil, will 5w-30 and 0w-20 cause problems if there is some residue 5w-30 oil.

Also any one use

$60 0w-20 oil Toyota/ exxon mobil Case of 6 Quarts Full Synthetic TGMO SN 0W-20 Oil

0w-20 oil, I have seen no one list it in forums. Sorry hijack this one just about to do an oil change and thought I would ask. 0w-20 is damn expensive 6L $60-80!!

 

60-80 for 6L sounds really expensive...Walmart sells Mobil1 for $7 a quart last I checked so that shouldn't be more than $40. Penn Ultra, IIRC, was the same price.

And do not worry about changing out to 0w20...it's perfectly compatible with other oils and the small amount left won't affect the blended viscosity enough to matter.

 

amsoil 0-30

 

Wrong... Amsoil is a group 4 oil (pure PAO's) and only uses a class-3 oil in one blend, which is the "XL-7500" blend.

 

No need to flush or do anything special. Your engine was and would be fine on 5w30, but if you want to go with the 0w20 (which should give you a little better economy) just change it. No flush or any special treatment necessary, just do a regular oil change.

 

i use mobil 1 , since i bought my truck, and had no problems, 5w30

 

Thanks JKD!

thats kinda what I though just didnt want to do anything foolish with this great TW site at my fingertips. I found an Amsoil guy down the street. I think I will check him out.

Can anyone tell me why 0w-20 is so damn expensive? do they just not make much of it or is it really that fancy?

 

As compared to what? At Walmart Mobil1 0w20 is the same price as any other Mobil1, which is pretty good usually. Penn Ultra is the same, as is Castrol Edge.

OW20 is typically a synthetic oil, so be careful not to compare to a petroleum oil that's not synthetic.

 

Provide some proof, because it's commonly known fact that PAO's do not dissolve additives, it's a basic property of the oil. The mavens of BITOG all agree AMSOIL probably has a heavy dose of PAO, but it's mostly a marketing thing as in use they aren't nearly as spectacular they once were. GpIII and III+ are just to good now and a lot of oils are performing so much better.

M1 isn't a pretty boy, but it does great is widely available and it's cheap at Walmart!

Oh...If you can provide proof you'll be the darling of BITOG!

brilliant

 

Interesting and indisputable but... marketing drivel.

Nothing there says it's 100% PAO, it just says it's 'formulated with PAO' that they are 'PAO based'. No one disputes that but...most all the major synthetic oil brands are formulated with PAO base stocks too!

Come on...didn't take critical reading in junior high school?

This completely ignores any facts about difference in relative performance of gp III+ synthetic and and gp IV synthetic, instead voicing their marketing department's hope that we continue to 'believe' them that the future belongs to PAO when it's becoming increasingly clear that the past belongs to PAO.

Really...AMSOIL may be a great oil, I won't dispute that. But this kind of marketing drivel, constantly offered up in lieu of certifications to industry specs and independent tests, is precisely the reason I wouldn't ever recommend them. They sound like snake oil salesmen...their product should deserve better than that but they prefer to sell it like Tupperware. They peddle a great product to the lowest common denominator and I feel so insulted and patronized by it.

Enjoy your oil, just don't try to allege others are inferior. There are many ways to skin a cat and the market place will find them all.

 

I've used Mobil 1 & Fram Filters for the last 5 yrs & put just about 200,000 mi on both of my vehicles. Used to deliver oil & additives to the refinery's. Let me tell you Mobil was by far the pickiest customer. They used to drain 10 gallons just for a single sample. Any particles or what appeared to be a drop of water and they would refuse all 5000 gallons. Their very meticulous about their product.

 

Mobil 1 EP. Over 200,000 miles. No problems.

 

You are right, and they are not completely PAO. I spoke to the head engineer over ther a few years back when I was investigation Mobil 1 and the "group III oils being passed off as Synths" legal battle. They told me they have a blend of group 3 and group 4, with an additive package as well. That is what I was told directly, so thats what I go on. Just thought this would help.
