Does the Magotan require 95-octane gasoline?
4 Answers
The Magotan requires 95-octane gasoline. Its direct-injection engine has relatively high requirements for gasoline, and it is recommended not to use 92-octane gasoline with too low an octane rating to prevent premature engine carbon buildup and knocking. The Magotan is equipped with two turbocharged engines: a 1.4T and a 2.0T, with the latter available in high- and low-power versions. The transmission system comes standard with a 7-speed dual-clutch transmission. Taking the 2020 Magotan as an example, its body dimensions are 4865mm in length, 1832mm in width, and 1471mm in height, with a wheelbase of 2871mm. In terms of suspension, the 2020 Magotan uses a MacPherson independent front suspension and a multi-link independent rear suspension.
I always emphasized this when mentoring apprentices at the 4S dealership - turbocharged engines like the Magotan must run on 95 octane. The fuel cap clearly states '95 octane or higher unleaded gasoline'. The EA888 engine has a high compression ratio, and using 92 octane can easily cause knocking. I had a client who cheaped out with 92 octane on the highway - the engine warning light came on within three days. Upon disassembly, we found pitting marks on the piston crowns. Long-term use of low-octane fuel leads to carbon buildup, knocking, and poor performance at best; at worst, it can melt pistons and require engine overhaul. Don't skimp on fuel costs, especially when running AC in summer - 92 octane is more likely to cause sluggish acceleration. If you must use 92 octane in an emergency, ease off the throttle and quickly mix in 95 octane to dilute it.
Buddy, I've been driving a Magotan for three years and I can tell you responsibly that you must use 95. When I first got the car, I was hesitant too, but after filling half a tank with 92 and driving on the elevated road, the engine shook like a massage chair. Volkswagen's turbo engines are quite delicate—the compression ratio of 9.6:1 isn't extremely high, but the direct injection system is very sensitive to fuel quality. A mechanic showed me with an endoscope that after running 2,000 km on 92, the valves had carbon deposits like candied haws. Now, I always check gas stations on my phone before refueling—95 often has promotions and isn't much more expensive than 92. If I go to remote areas, I always keep two bottles of fuel additive in the trunk for emergencies.
The instruction manual clearly states on page 172: Fuel grade 95 (RON). My father-in-law, who has run an auto repair shop for thirty years, says German cars have small design margins, and insufficient octane can cause pre-ignition. Although the engine ECU can fine-tune the ignition timing, it's like making someone eat leftovers every day—they'll get sick eventually. Be careful not to be fooled when refueling; some small gas stations mix 92-grade fuel into their 95-grade tanks. Here's a down-to-earth method: after refueling, listen for a metallic knocking sound during a cold start—that indicates poor fuel quality. Don’t skimp; replacing a set of fuel injectors costs as much as three years’ worth of 95-grade fuel.
