Many 5Ws need a little synthetic these days, to meet strict government specs.
I too think Chevron makes good products … but they are getting a bit creative with the “Isosyn” term on Delo … when you see that on 15w40 for $13/jug … ya reckon there is much synthetic in that?
ISOSYN ADVANCED TECHNOLOGY
ISOSYN Advanced Technology is the combination of Chevron’s outstanding formulating expertise, unique high performance additive chemistry and premium base oils that helps extend the durability of critical diesel engine parts.
Delo 400 products formulated with ISOSYN Advanced Technology can provide improved engine longevity, extended oil drain performance, and excellent diesel component parts protection, helping to extend vehicle life and minimize total cost of ownership when compared with previous generation Chevron HDMO formulations.
ISOSYN Advanced Technology benefits customers by helping to provide:
• Up to 35% improved oil oxidation control*
• Up to 68% improved wear protection*
• Up to 64% improved piston deposit control*
*Results will vary based on the particular Delo 400 product, operating conditions, and engine
types. Always follow OEM recommendations and utilize used oil analysis testing when extending oil drain intervals.
FUNCTIONS
Delo 400 SDE SAE 15W-40 with ISOSYN Advanced Technology helps keep rings clean and free for maximum combustion pressure and minimal wear. Delo 400 SDE SAE 15W-40 minimizes valve and piston crown land deposits, thereby maintaining minimal oil consumption. Its high level of ashless dispersants keep fuel soot in suspension and help avoid filter plugging, heavy cylinder head sludge, abrasive polishing wear, high viscosity increase, and oil gelling. These problems can result in excessive engine wear and bearing failure on startup, without prior indication to the operator. Specially selected oxidation inhibitors control oxidation, sludge, and undue thickening during oil drain periods.
Delo 400 SDE SAE 15W-40’s unique antiwear additive protects against valve train wear and scuffing of highly loaded parts operating under boundary lubrication. A specially selected viscosity index improver ensures easy flow at low temperatures and excellent film protection in hot engine areas.
The combination of premium dispersant additives and ISOSYN Advanced Technology allows Delo 400 SDE SAE 15W-40 to effectively disperse soot and keep it in suspension. This minimizes the risk of valve train wear, lever polishing, and filter plugging.
