Same oil for gas and diesel

[MonsterTDI09]

Mobil 1 5/30 ESP said it's 507 approved. It also said it can be used for VW gas engine 504. To me this doesn't sound right. Is this oil for the Europe market? Experts chime in please.

Motul Specific has the same specs, 504 and 507.

What is it in a 507 oil that you think is incompatible with gasoline engines?

I have no clue. I was thinking it was more for the gas engine than a diesel.
So the oil doesn't keep the soot in suspension.

You can run either oil in either engine type. It's better to use specific oils for their respective engines, but I know a lot of people run stuff like Rotella T6 synth in the 2.0T because of all the detergents and such it has in it, and the heavier weight is better during the summer for the turbo and such.

Lots of oils have VW approvals for gas and diesel engines.

VW spec 505.1 is also 502 for gasoline engines . What is the issue here? VW has always combined spec for both gas and diesel engines. Can you imagine the nightmare the dealerships would have if they didn't. Just because it holds soot doesn't mean it won't work well in a gasoline engine.

Oils intended for gasoline engines often are inadequate for diesel due to inability to keep soot in suspension. Some of the old diesel oils pre 2007 had high TBN numbers to deal with sulfuric acid in the oil caused by burning higher sulfur diesel fuel. But since the adoption of ULSD, the TBN numbers in diesel oil have been reduced, as less sulfur in the fuel means less sulfuric acid produced.

But even in the old days, the diesel oils usually also had a high spark engine rating, and were sold commercially as "all fleet" oils that could be used in both the gasoline and diesel vehicles in a motor pool. Also, in the old days, gasoline vehicles had catalyst, and diesels did not, so potentially there could be a concern that something in the diesel oil could poison the catalyst in a gasoline vehicle. But these days, both diesels and gasoline vehicles have catalyst.

Please define old days and I am 60 years old and don't remember when it was ill advised to use a diesel rated oil in a gasoline engine. Now that being said it was ill advised to use a gasoline only rated oil in a diesel engine. Correct me if I'm wrong. These days with VW approved oils they are one in the same. BTW my first diesel powered car was a 67 MB 200D and it was sure no hot rod. Just showin' my age.

Monster,
What oil do you use in your car? What is the VW approved rating of it.

I am older than you. But around 2006, the EPA reduced the amount of ZDDP (zinc) allowed in SM oil because too much ZDDP was impairing catalysts in gasoline powered cars.

"The main use of ZDDP is in anti-wear additives to lubricants such as greases, gear oils, and motor oils, which often contain less than 1% of this additive. It has been reported that zinc and phosphorus emissions may damage catalytic converters and standard formulations of lubricating oils for gasoline engines now have reduced amounts of the additive, though diesel engine oils remain at higher levels."

Castrol edge pro 5w-30 VW 504 /507.I didn't think of looking on my bottle oil think it was for diesel only. I didn't 504 was for gasser now I know.

Then why do they still have oil for diesel only?

 

[k1xv]

I don't think that there are many oils any more that are diesel only. Look at the SAE ratings. Diesel oils have ratings that start with the letter C. Such as CI-4 or CH. Oil rated for gasoline engines start with an S, such as SM or SN. If it has an S rating as well as a C rating, it can be used in a gasoline engine.

when VW created the new consolidated 504/507 standard, they created it in tandem, primarily to keep up with demands for the European emissions standards.

So, in Europe...
504 was suitable for 502.00, 503.00 & 503.01
507 was suitable for 505.00, 505.01, 506.00 & 506.01 (though the Touareg V10 & I5 was initially not suitable).

likewise, many of the diesel spec oils also met gas spec, so it was common for VW to have 502.00/505.00, 502.00/505.01, 503.00/506.00/506.01, etc.

501.01 was revived and paired with 505.00 for the Audi R8 GT, 10w60, G 052 194 1L DSP

so... yes, gasoline spec oils were also used in TDI's, certain ones also met TDI-specific specifications

Many on the motorcycle forum I am on ( http://forum.cog-online.org/index.php ) use either Rotella T6 or M1 TDT 5w-40 oil in their 1000cc Kawasaki sport touring motorcycle engines, as well as many others. T6 actually carries a JASO rating requirement for these types. I was skeptical at first, but the maintainence records of many users was great, so now I have one less oil to stock on the garage shelves.
