by Oilem Published on Thursday, July 30th, 2020

It is an almost certainty that the user manual of any new vehicle you purchase will stipulate a running-in period usually of 1,000 miles or more.

Restore Compression Loss & Remove Engine Glaze

by Oilem Published on Thursday, April 30th, 2020

There are numerous causes of cylinder compression loss. The first is poor engine break-in. If you haven’t already done so we recommend you read our guide on “Engine Break-in” HERE.

by Oilem Published on Thursday, March 21st, 2019

by Oilem Published on Monday, January 16th, 2017

I will keep this brief because it is very simple. Take any branded diesel fuel. What is the difference between that brand’s standard EN590 diesel and super/premium diesel that you pay an extra 8-10p more per litre for? 1. Additional deposit control detergent. 2. Additional 2-Ethylhexyl nitrate (2-EHN) cetane improver. That is it. The additional […]

Improving Miles Per Gallon (MPG) Via Driving Style 1. Don’t drive too fast or accelerate too hard. Wind resistance increases drastically with increasing speed.

Reducing Vehicle Emissions

by Oilem Published on Tuesday, January 5th, 2016

All vehicles produce emissions as fossil fuel is burned and converted into energy. Unfortunately, like most other emissions, these usually end up in the atmosphere.

They cause […]

There are now a multitude of companies that will remap the ECU on your vehicle.

Why are ECU / Engine Remaps and Tuning Boxes so Effective?

by Oilem Published on Thursday, April 30th, 2015

When one purchases a vehicle they likely expect engine ECUs to be optimally mapped prior to sale. While they are normally very well mapped, whether or not it is done in an optimum way is very subjective. In this article I will look at engine/ECU remapping and chipping and the use of tuning boxes. Particularly, […]

Using Fuel Additives at Higher Dosages - Overdosing

by Oilem Published on Friday, March 13th, 2015

A question I am regularly asked is whether fuel additives can be added at a higher dose or added to less fuel in order to make a stronger concentrate, and whether this is more beneficial. The answer in most cases is no. This is because additives are specifically designed to work with a certain amount […]

Garages & Repair Centers Using Cheap Oil

by Oilem Published on Friday, March 13th, 2015

There is a “cheap oil” endemic and I am concerned for the consumer. As distributers of various lubricants, one of our tasks is to demonstrate to automatic transmission and gearbox rebuild specialists the benefits of using OE (original equipment) oils or at least lubricants that meet the required manufacturer’s specifications. This is much more difficult […]

by Oilem Published on Thursday, February 12th, 2015

When examining the field of products, services, and techniques that promise to increase MPG, you find a confusing minefield, at best.

Engine & Fuel System Cleaning Machines – A Review

by Oilem Published on Friday, November 14th, 2014

I am regularly asked for comment on a particular engine (fuel system) cleaning system that is endorsed by a well-known TV celebrity mechanic. Does the product work? Well actually, yes it does.
