What is the difference between Quartz 5000 and 7000?

[McKatherine]

Quartz 7000 performs better in terms of low fuel consumption and cold-start performance, while Quartz 5000 has slightly better anti-wear and anti-corrosion properties. Both Quartz 5000 and Quartz 7000 are Total's semi-synthetic lubricants, but Quartz 5000 is slightly lower in grade compared to Quartz 7000. Even though both have an API rating of SN, Quartz 5000 also has two SM ratings. In terms of cost-performance ratio, Quartz 5000 is higher than Quartz 7000. Quartz 7000: Although Quartz 7000 is a semi-synthetic lubricant, it also features smooth performance in reducing fuel consumption and cold starts. Even under harsh driving conditions, it ensures excellent engine power performance. Additionally, Quartz 7000 offers good anti-wear protection and long-lasting engine cleaning performance. Quartz 7000 has an API rating of SN and comes in two viscosity grades: 5W-30 and 10W-40. Quartz 5000: Like Quartz 7000, Quartz 5000 also has advantages such as reduced fuel consumption and smooth cold starts. It also features excellent anti-wear and anti-corrosion properties, as well as protection for turbochargers. It can be understood as the predecessor to Quartz 7000, with slightly lower performance. Its API and viscosity grades are SN 5W-30, SN 10W-40, SM 5W-30, and SM 10W-40.

As a seasoned driver who has used various engine oils for over a decade, I find the difference between QUARTZ 5000 and 7000 quite clear: 5000 is a semi-synthetic oil, suitable for changes every 5,000 kilometers, and it's affordable and economical. I find it perfect for daily commuting. The 7000 is upgraded to full synthetic, capable of lasting 7,000 kilometers, with more advanced additives like rust prevention and oxidation resistance, offering better engine protection at high temperatures, though it costs a few dozen yuan more. When I use 7000 for long-distance driving, the engine responds smoothly with less noise. I recommend 7000 for those who frequently drive on highways to save maintenance effort, while 5000 is sufficient for city commuting. Don’t overlook regular maintenance as it can extend your car's lifespan. Also, always check your vehicle’s manual to choose the right specification and avoid unnecessary upgrades to prevent wasting money.

I have some knowledge about motor oil composition: Quartz 5000 is based on semi-synthetic oil with moderate viscosity, sufficient for regular use; Quartz 7000 switches to a full synthetic formula that better withstands high temperatures and wear, with higher API standards suitable for newer engines. After using 7000 for an oil change, I noticed smoother starts and a slight reduction in fuel consumption. The price difference is noticeable but worth it long-term due to extended engine life and savings on repair costs. Driving habits matter greatly: for aggressive driving, 7000 is safer. Similar distinctions exist among Mobil products—don't switch blindly. Always use what's specified in the manual and avoid over-matching.

When I first started driving, I was also curious about the difference between FastRun 5000 and 7000. It actually comes down to the oil change intervals: the 5000 km option is cheaper, while the 7000 km one lasts longer with fewer service visits. I find the 5000 works great for city driving—keeps the engine smooth. My friend, who does long-distance trips, prefers the 7000 for better engine protection and anti-aging additives. It's pricier but worth it if you drive often. New drivers should stick to the manufacturer's recommendation and not push the mileage limits.

My budget is tight, comparing FastRun 5000 and 7000: 5000 is cheaper and durable enough for 5000 km, suitable for low-mileage drivers like me; 7000 is fully synthetic, offers stronger engine protection, extends lifespan but costs 20% more. I've used 5000 for years with no issues, switching to 7000 gives smoother acceleration. Cost-effectiveness depends on driving frequency – frequent drivers should opt for 7000, it saves on maintenance long-term. The additive difference makes 7000 more reliable in harsh conditions. Saving money is key – choose according to your means.
