ExxonMobil · Mobilgard™ Marine · Authorised Distributor — South Africa

Mobilgard™ M330 is a premium, extra high performance 30 TBN SAE 30 trunk piston engine oil (TPEO) — part of the Mobilgard M30 Series and the lighter viscosity grade companion to the Mobilgard M430 (SAE 40). Designed for medium-speed diesel engines operating on residual fuels where the OEM specifies an SAE 30 grade lubricant, M330 delivers the same outstanding residual fuel compatibility, excellent engine cleanliness and exceptional TBN retention as the M430 — in a lighter SAE 30 viscosity grade for engines specifying lower operating viscosity. Developed using ExxonMobil's patented DAC (Detecting Asphaltene Contamination) test technology. Available through Orbit Industrial — authorised Mobil distributor, South Africa.

M330 vs M430 — Grade Selection

Both grades share the same 30 BN formulation and OEM approvals — select by viscosity

Mobilgard™ M330 — SAE 30

  • Medium-speed engines where OEM specifies SAE 30 grade
  • Higher-speed medium-speed engines requiring lower operating viscosity
  • Engines operating at higher ambient temperatures where SAE 30 is preferred
  • KV @ 100°C: ~11.5 cSt

Mobilgard™ M430 — SAE 40

  • Medium-speed engines where OEM specifies SAE 40 grade
  • Most common TPEO specification — the standard residual fuel grade
  • Higher load applications requiring heavier viscosity grade
  • KV @ 100°C: ~14.8 cSt

Always confirm grade with your OEM handbook. Contact Orbit Industrial for application-specific grade selection. View Mobilgard M430 (SAE 40) →

Features & Benefits

Outstanding Residual Fuel Compatibility

High performance additive detergent technology provides outstanding fuel-lube compatibility — reducing sludge formation from asphaltene contamination and enabling longer oil life in residual-fuelled medium-speed engines specifying SAE 30 grade.

Excellent Engine Cleanliness

Reduced deposits in piston undercrown and ring belt areas — keeping crankcase, camshaft and piston areas clean for extended periods between overhauls in the most severe residual-fuelled medium-speed SAE 30 applications.

High Performance Thermal & Oxidation Stability

Excellent TBN retention and resistance to viscosity increase over long operating periods — maintaining consistent engine protection through extended drain intervals in severe service medium-speed marine diesel applications.

Excellent Lube-Fuel Compatibility

Outstanding lube-fuel compatibility and easy water separation — critical for vessels operating on a range of residual fuel qualities through different South African and international ports.

ExxonMobil Patented DAC Test

Developed using ExxonMobil's patented DAC (Detecting Asphaltene Contamination) test — providing an early warning system for asphaltene contamination that, left undetected, could cause piston damage and excessive oil consumption.

Rust & Corrosion Protection

Outstanding rust and corrosion protection — protecting critical wear surfaces from water and acidic corrosion in residual-fuelled medium-speed engines operating in the marine environment through all weather conditions.

Recommended Applications

Deep-Sea Vessel Main Propulsion

Main propulsion engines on deep-sea bulk carriers, tankers and container ships — where the OEM specifies SAE 30 grade trunk piston engine oil for medium-speed residual fuel engines.

Coastal & River Ships

Main propulsion engines on coastal and river ships operating in South African coastal waters — MAN ES and Wärtsilä medium-speed engines where SAE 30 TPEO is specified.

Stationary Power Plants

Medium-speed stationary diesel engines in power generation and industrial applications where 30 BN SAE 30 residual fuel engine oil is specified by the OEM.

Ok product for average shape
Size: Large, Color: White
ok for the price but didn't work out for us. I had one guy whose body is thick and one who is thin. Couldn't get the set to fit on top and bottom at the same time, pants were a lil see through, but still decent quality and price.
