Opinions on Mobil 1 0-40 or Amsoil 0-anything for R-Spec?

[EXBMWGUY]

The synthetic 0-xx viscosity weights are not mentioned anywhere in Hyundai documentation. I am thinking M-1 European formula would be excellent for any of the Genesis motors. I live in Minnesota. Thoughts?

If I remember correctly, I think Mark888 stated that European formula oil should not be used in the Genesis, but we'll wait for him to chime in for more info.

What does the owners manual recommend? Stay with that.
Mobil-1 is an excellent true synthetic. Amzoil has some additional benefits, but unless you plan to run extended (20k+) miles between oil changes, it is probably not worth the extra money.

There is no need for the 0W-40 European formula in the Tau 5.0. The manual asks for 5W-20 or 5W-30. I am using Mobil 1 0W-20 AFE, that I got on sale. It has one of the lowest MRV's I have ever seen (what the F is MRV?)

[URL="http://www.mobiloil.com/USA-English/MotorOil/Car_Care/AskMobil/Explain_MRV_Rating_for_Motor_Oil_Pumpability.aspx"]"AnswerAsk Mobil Archive :

MRV @-40°C, which stands for Mini-Rotary Viscometer, is a lab test that measures the oil's ability to flow (pumpability) at -40°C. The lower the viscosity grade, the lower the temperature at which the oil will pump. For example, a 0W oil will pump at temperatures 10° colder than a 10W oil and
20° colder than a 20W oil.

0W-20 AFE - MRV 9200
0W-40 Euro - MRV 31,000

As scottdk mentioned, you should not use a European Formula Oil in the Genesis, or any Japanese or American car. Sometimes it is hard to tell which is a European Formula Oil, but most manufactuerers list that on the bottle.

Mobil 1 0W-20 AFE (Advanced Fuel Economy) is OK for Genesis
Mobil 1 0W-30 AFE is OK (what I use)
Mobil 1 0W-40 is a European Formula oil for BMW, MB, etc and not OK
Castrol Syntec 0W-30 - Last I saw it was a European Forumua Oil and not OK
Castrol Edge - Not sure if they have a suitable 0W oil for Genesis.
Amsoil - Check the specs on their website.

European Forumula Oils are formulated with low sulfated ash, phosphorus and sulfur (SAPS) for environmental reasons and are specified by BMW, MB, VW, and a few others, and the engines need to be designed for such formulas. In addition, they tend to get lower MPG than other oils.

Keep in mind that Amsoil sells several different grades of oil. Some are comparable to regular synthetics like the competition from major oil companies, and some are "high-end" synthetics with 100% Group IV-V base stocks, but are very expensive. Plus, if your engine is under warranty, you must change the oil at least every 7500 miles anyway.

Many people read the glowing reviews and long service life of the very expensive Amsoil stuff, but then buy the lower quality Amsoil that is made from Group III synthetics. which is not even as good as Mobil 1 or Castrol Edge, even though it is more expensive than either of these oils from the majors.

 

[TJPark01]

In addition to Marks comments:
Castrol Edge Titanium makes a 0W-20 Edge product as well as 5W-20 or 5W-30 that can be used on the 5.0 Tau. Will the 0W-40 or other Euro spec oils work in the Genesis, yes, but they are not optimal formulas. What you will typically see is worse gas mileage.
Since the price is typically the same there's no reason to deviate. Since your engine is under warranty you're not going to benefit from boutique oils that claim 15k mile oil changes when the warranty specs 7500 miles.
Is Mobil 1 0W-40 Okay to Use in a Ford F-350?

Great information, thank you. "Bob the Oil Guy" isn't the ONLY oil guy!

Beinga n Ex BMW guy myself - I used the Castrol synthetic 5w30 in the ZHP and use it for the R Spec-

Great oil as you know - no need to go to a 0w oil

The M5 used the 0w-60 - which I had to buy at the dealers fo 10 bucks a quart - that hurt....LOL

I've only ever seen the High End expensive Amzoil products here in Canada. I didn't realise they made lower quality Group-III synthetic oils. Good to know. I also agree with your other comments that with regular oil changes there is no point in using high-end oils as the benefits could never justify the cost.

Ended up buying Castrol Edge with Titanium 5w-30 at Walmart today. They have a 5-qt. container @ $30.78 ea. and 1-qt. @ $8.53 ea. Buying it like that makes it a pretty insignificant premium I think.

Hopefully it doesn't actually have any titanium in the oil

Those 5-quart containers of oil at Walmart are a great bargin and available for most major brands/grades. I use the Mobil 1 0W-30 AFE which costs about $25 for a 5-quart jug. I think that Mobil 1 Extended Performance is about same price as Castol Edge, which really just provides an extended drain interval of up to 15,000 miles, but I change my oil too often to take advantage of that.

I think we should petition Hyundai to start providing a Titanium Oil Additive Detector (TOAD) with every car they deliver.

The reference to titanium is, of course, titanium fluid strength technology, not that real titanium is in the oil (which would destroy the engine within a rather short time). A very unfortunate piece of marketing IMO. But I guess that is to be expected from BP.
