BG 245: Premium Diesel Fuel System Cleaner
325 ml
New improved chemistry for modern higher pressure diesels
Sister product to BG 244 from BG Products, BG 245 is a newer premium fuel system cleaner for diesel systems. The BG range is regarded by professionals as the best fuel system cleaners of their kind.
Today’s diesels can produce more power with less fuel than ever before. Injector tips in High Pressure Common Rail injection (HPCR) systems are designed to handle produce twice as much injection pressure as mechanical fuel injection. However, diesel fuel is not, being notoriously inconsistent and therefore a threat to HPCR systems. Injector deposits at a miniscule quantity can cause sticking and carbon begins laying on the fuel filter until it reaches a point of plugging.
New BG 245 Premium Diesel Fuel System Cleaner removes and dissolves deposits from the entire diesel injection system, including inside fuel injectors and combustion chambers. Plus, BG 245 contains a fuel lubricity agent to protect components from wear and cetane improver for cold starts.

BG DOC: Diesel Oil Conditioner, 325ml
325 ml
BG DOC Diesel Oil Conditioner is designed to condition oil in modern high-output diesel engines.
Modern diesel engines operate at high temperatures and pressures. This puts a lot of demand on diesel engine oils and the additives they contain. Hydraulically activated fuel injectors increase oil pressures and emissions devices increase soot accumulation in oil. These systems test the limits of engine oil. Under the right conditions, heat causes sulphur from fuel to combine with entrained moisture to create sulfuric acid. This acid wreaks havoc on engines, causing corrosive wear and severe damage to engine components.
BG DOC Diesel Oil Conditioner maintains like-new diesel engine power and performance, neutralises acids and acid corrosion, reduces friction and wear on engine parts, stabilises viscosity, prevents sludge through increased oxidation and soot control.

BG EPR: Engine Performance and Compression Restorer, 325ml
325ml
A revolutionary formula with proven “ring-clean” technology. BG 109 Engine Performance Restoration is a quick and effective blend of cleaners that will soften, emulsify and dissolve those hard to remove fuel gums that clog rings and will usually do it in 15 minutes or less.
Modern engines operate at high temperatures. Combined with prolonged drain intervals and reduced engine cooling, automotive engine oil is under a lot of stress. Continuous thermal and oxidative breakdown contributes to oil thickening, heat retention and deposit formation. Heavy deposits can impede normal piston-ring function; thus reducing fuel economy, lowering power output, and increasing harmful exhaust emissions and oil consumption. Compression will increase with removal of these deposits.
Safe for use in petrol, diesel and rotary engines.

BG MOA: Engine Oil Supplement Advanced Formula
325 ml
BG MOA Advanced Formula Engine Oil Conditioner is designed to enhance engine oil and extend engine oil life. The unique blend of additives in the product maintains engine cleanliness and performance under high load conditions.
Modern operating conditions of a car in the urban cycle (warm-ups, start-stop, short trips, extended intervals between oil changes) and high operating temperatures lead to a rapid depletion of the required additive package in the engine oil. This leads to the accumulation of more unburned fuel and other combustion products in the engine oil, which leads to the rapid oxidation of engine oils. Oxidation causes oil to thicken and deposits in the crankcase, oil filter, oil passages and other critical internal engine surfaces.
BG Advanced Formula MOA® Engine Oil Conditioner is designed to maximize the performance of synthetic and mineral engine oils and extend engine oil life.
The product prevents oxidation and an increase in the viscosity of the engine oil even under high load conditions.
Keeps compression rings, lifters, tensioners and other engine components clean for long engine life and lowers maintenance costs.
Excellent for gasoline engine use.
Compatible with synthetic and mineral motor oils.
Benefits:
increases the strength of the oil film
prevents oxidation and oil thickening
prevents the formation of sludge and varnish deposits when driving in the urban cycle
protects against rust and corrosion
provides increased power and performance
reduces harmful emissions into the atmosphere
Excellent long-term protection of engine parts against wear!
Used by:
Restoring the elasticity of the elements of the oil system of a gasoline engine
Restoring the elasticity of the elements of the oil system of a diesel engine
Engine oil protection
Mode of application:
For continuous engine protection, add one can (325 ml) of 4-5 liters of engine oil at every oil change
Add to the crankcase in the event of a drop in the oil level to enhance its properties between replacements
Do not overfill the crankcase
