What is ISOSYN® Technology?
ISOSYN Technology is Delo's Differientiator. ISOSYN Technology represents decades of experience in diesel engine parts protection, and it is how we formulate our top-tier Delo® products. Using our expertise and experience, we combine premium base oils with high-performance additives to deliver engine parts protection that rivals synthetics. This unique combination gives Delo customers the performance advantage.
ISOSYN vs Conventional
Rather than using conventional solvent dewaxing technology, we make base oils with Chevron’s ISOCRACKING and ISODEWAXING catalyst. Our high-performance additive formulation provides superb soot dispersion and prevents deposit build-up. Combining our formulation with ISOSYN Technology provides Delo customers with protection, performance, and confidence.
Base oils are made with ISOCRACKING and ISODEWAXING catalysts.
We add high-performance additives that deliver excellent soot dispersancy and prevent buildup.
The combination keeps engines clean for miles.
Conventional Solvent Dewaxing Base Oils.
Additives for economical heavy-duty lubricants don’t deliver the soot dispersancy Delo does.
Sludge and deposit buildup with conventional oil base products.
