Several well-known models, including the Primera, Sunny, and Sylphy, were equipped with the 1.8-liter Nissan QG18DD engine, which was manufactured at the company’s Japanese facility between 1999 and 2007. Because of its strict fuel quality requirements, this unit got bad reviews.
Internal combustion engines QG13DE, QG15DE, QG16DE, and QG18DE are also part of the QG family.
The engine was mounted on:
- Nissan Bluebird Sylphy N16 in 2000 – 2005;
- Nissan Primera 2 (P11) in 1999 – 2002;
- Nissan Primera 3 (P12) in 2001 – 2007;
- Nissan Sunny 5 (B15) in 1999 – 2006.

Disadvantages of the QG18DD engine
This engine has a very soft high pressure fuel pump and is very picky about fuel quality;
The motor frequently experiences traction failures as a result of another clogged filter;
Sometimes the timing chain does not even reach 150,000 kilometers because it is pulled out rather quickly;
A progressive oil burn frequently starts on runs longer than 100,000 kilometers;
There are instances where the catalyst is destroyed, allowing its crumbs to enter the cylinders.
