Just bought a 2013 4 cyl Accord. Two dealers said they used Mobil semi-syn 0W-20 oil in new car and also for oil changes. Didn't know Mobil made such an oil. Secondly, why would they use semi-syn anyway?

Didn't know they made a 0w-20 blend either. They use a blend to save $ and save the customer $.

The Mobil website says they only make full synthetics in this space. Perhaps the dealer is referring to the Honda branded oil. If this were my car, I would spend the extra dough for full synthetic.
 
Mobil 1 Advanced Fuel Economy is usually $24.97 for a 5 qt jug at Walmart. Full synthetic and meets your vehicle requirements. Lots of big brands are working on a Synthetic Blend 0w20. Honda itself sells the syn blend version in qts too. Castrol , Ashland , Kendall are some of those big brands.
 
Nothing really wrong with semi-syn in a non turbo app - especially given that the Mobil 1 0w20 and Pennzoil Platinum 0w20 are NOT real syn anyway - only majority group III. They both (only) meet ILSAC GF5 for use with OLM.As always, adjust OCI to driving style as needed.

C'mon... what common name oil brand, found at our typical national auto-parts stores, plus places like Walmart, KMart, Target, Meijer...etc.... sells 100% Group 4 oil?

What is your definition of true-blue, full synthetic?

The guy that told you such is mistaken.
 
Sounds like the dealership likes to mix and blend oils. Some M1 and Mobil Super. Can't be bad....might be better than 1 oil alone...as long as it saved you some $$$ I'd be happy.

According to the Japanese PDS, Mobil 1 0w20 is ~40% PAO......

Not that it matters of course in your crusade.

I think he meant Grp IV's like Amsoil AZO,ASM,ASL etc. and Grp V's like RedLine, RLI, MOTUL.

Anyhoo, I would not hesitate to use Mobil 1 0w20 (an excellent oil that is easy to come by on sale) and call it a day. There is Mobil Super-Synthetic 0w20, maybe that is what they meant. It has not been out for long so I doubt it though.

Sounds like your shopping at the wrong places for a synthetic

but, no place or oil company sells 100% group iv oil - unless you are buying bulk stock to blend. I'm not saying thats what you want (real syn) I'm saying you arent buying synthetic - you are buying a syn blend (at best) when you buy ILSAC "fully synthetic" oil". So its a moot argument about CP/Honda semisyn vs M1 vs PP vs Quaker State Ultimate Durability etc. Look at specs, not worthless add copy. BTW ELF found through extensive track experience that syn blend work better (lubricity) than majority group iv base.

TAYQ: 0w30 BP Castrol showing MB and BMW LL gasoline approvals should still be be majority iv/v base oil with high HTHS and low pour point and good ccs and mrv (below -50). BP's latest TDS for EDGE with Syntec appear top have wrong./conflicting data for this oil.

Correct.
The dealers simply don't know that it is Conoco-Phillips and not Mobil that makes the two Honda USA 0W-20 Full Synthetic and 0W-20 syn-blend oils.
And btw both oils have virtually identical VOAs , so figure that one out.
 
Mobil do make 0W20 weight oil whether they call blend or synthetic. The dealer can use other oil instead of CP blend as long as they meet manufacturer requirement. Most so called synthetic oil on the market are just Group III for cost purpose. However, group III oil performance are close to group IV. For Honda Accord I4 K24 engine, UOA show good result with syn-blend such as Motorcraft 5W20 and 0w20. I am sure Moil One 0W20 (Honda now uses 0W20) will also show good result
 
Perhaps I can find a good deal on that "Heavenly Toyoto" oil that folks seem to like so well. I have no intention of using the dealer oil since I do my own changes, but am more curious why they use a semi_syn than about who makes it.

According to Pablo not even Amsoil is 100% grp 4. I'm not sure any oil is 100% anything.

To my knowledge Motor Craft does not have a 0-20.

Royal purple said they were group 4/5 in the hps line or one of their lines of oils iirc.
 
The Accord 4 cyl is a new '13. I'm thinking of changing out the original oil around 3-4K. Does that sound about right? I've only got 600mi on it now so it will be a while.
