What is DH oil?
Product Description. Mobil Delvac Super DH-2 10W-30 and 15W-40 are high performance, heavy duty engine oils that provide proven protection to diesel engines operating in severe on -highway applications using low sulfur fuel.
Which is better C1 or C2 oil?
In Europe, according to the ACEA, low ash oil is labelled as C1 (0.5% ash), C2 (0.8% ash – better suited to higher performance engines) and C3.
What does SG in oil mean?
specific gravity
Liquids with a density lower than water, which includes most crude oil grades and petroleum products, will have a specific gravity between 0.0 and 1.0. In the oil industry, specific gravity is a common quality specification for finished products.
What is SG or SH oil?
SG -Obsolete, not suitable for engines built after 1993. SH – Obsolete, not suitable for engines built after 1996.
What does Jaso dh 2 mean?
JASO DH-2: A low sulphated ash oil designed for the lubrication of Heavy Duty Diesel Engines, particularly when equipped with exhaust after treatment devices. JASO GLV-1: An ultra-low viscosity, fuel saving, passenger car engine oil.
What does Jaso stand for?
Japanese Automotive Standards Organization
In 1998 the Japanese Automotive Standards Organization (or JASO for short) developed a grading system for motorcycle oils. The grading system measured (amongst other things) an oils ability to resist clutch friction (or slippage), protection offered against engine wear and pitting in the gear box.
Can I use C3 instead of C1?
ACEA C grade oils are for the most, not interchangeable with one another depending on the particular applications. e.g. An ACEA C1 engine oil, cannot be used where an ACEA C3 oil is specified by the manufacturer as the C1 has a lower Sulphated Ash requirement than a C3 oil.
What does ACEA A1 B1 mean?
ACEA A1 / B1 specification is intended to be used in petrol engines (normally cars and vans) or light duty diesel engines with an extended service interval. The A1 / B1 specification directly indicates that the oil has low friction, high temperature / high sheer characteristics, ideal for the older type engines.
Which is better Ma or MA2?
If some results fall within the MA1 subcategory but others fall under MA2, the oil is simply classified as JASO MA….JASO MA: How are results reported?
| JASO MA1 Oil | JASO MA2 Oil | |
|---|---|---|
| Static Friction Characteristic Index (SFI) | ≥1.15 and <1.7 | ≥1.7 and <2.5 |
| Stop Time Index (STI) | ≥1.55 and <1.9 | ≥1.9 and <2.5 |
Is MA2 oil better than Ma?
In 2006, MA1 and MA2 were added as extra categories within the JASO MA specification. The main difference between these two categories is the higher friction performance MA2 oils are delivering.
What oils are JASO certified?
Some motorcycles oils known to meet JASO standards:
- JASO MA2: Mobil SUPER MOTO 4T MX 10W-30.
- JASO MA2: Motul 3000 Plus 4T 10W-40.
- JASO MA: Castrol POWER1 4T 10W-40.
- JASO MB: Mobil SUPER MOTO Scooter MX 10W-30.
Is amsoil JASO certified?
Official JASO approval PDF Amsoil is NOT JASO MA2 certified, their labeling just says “exceeds” I send them an e-mail about it and received a little attitute saying that they don’t have to be certified by JASO . Their labeling does not meet JASO standards and they don’t list certification # on the bottle.
Is C4 oil better than C3?
C4 is a lower “SAPS” oil (Sulphated Ash, Phosphorous, Sulphur) specifically compatible with exhaust after-treatments such as DEF. C3 actually has better lubricity properties (because SAPS are a good thing extreme-pressure-wise), but may effect emissions.
Is C1 oil better than C3?
Can I use SL oil instead of SN?
SM and SN supersedes SL so both oils can be used.
What is SL oil?
Special Synthetic Lubricants It is a series of high quality, shear-stable, multigrade engine oil for use in a wide range of passenger car and light-duty commercial vehicle engines where API SL performance lubricants are required.
