1. Introduction to the V35A-FTS Engine

The V35A-FTS engine is Toyota’s groundbreaking 3.5-liter V6 twin turbocharged Dynamic Force engine. What is it for? Bring in a smaller displacement engine to replace the larger ones with something small yet fuel-efficient, and still so powerful.

It employs direct and port fuel injection (D-4ST), twin turbochargers, and VVT-iW (Variable Valve Timing – intelligent Wide) to deliver breathtaking power with amazingly good fuel economy and emissions.

Stock or tuned, the engine is famous for:

• Breathtaking torque and power
• Legendary tunability
• Boost longevity
• Enhanced turbo response

If you’re shopping for a V35A-FTS engine, we have OEM and tuned ones available for most platforms.

3. Why Oil Selection Matters in Tuned V35A-FTS Engines

Tuning takes an engine beyond its stock specifications. With increased boost, increased combustion rates, and increased internal component stress, engine oil selection becomes critical to performance and longevity.

Here’s why:

• Increased boost and RPMs raise oil temperature and shear stress
• Turbochargers require clean, high-flow oil to avoid coking or bearing seizure
• Dirty or thin oil causes premature wear
• Incorrect viscosity affects oil pressure and turbo health

For stock operation, Toyota has guidelines. But if your V35A-FTS is performance-tuned, oil specs may differ depending on power levels and whether it’s a street or track build.

4. V35A-FTS Engine Recommended Engine Oils (OEM & Tuned Builds)

✅ OEM/Stock Setup – Toyota Recommendations

For stock engines, Toyota suggests:

• Oil Grade: SAE 0W-20 (API SN/SM or later, ILSAC GF-6)
• Synthetic Only: Full synthetic oil only
• Brands: Toyota Genuine Motor Oil, Mobil 1, Castrol EDGE, or equivalent

These oils provide:

• Low viscosity for fuel efficiency
• Good turbo system protection
• Toyota spec quality

---

✅ Mild Tuned (Up to 500 HP)

For light tune and increased boost:

• Recommended Grade: SAE 5W-30 or 0W-40

Top Oils:

• Motul 8100 X-Cess 5W-40
• Liqui Moly Leichtlauf High Tech 5W-40
• Amsoil Signature Series 5W-30
• Mobil 1 FS 0W-40 (European Car Formula)

These oils provide improved heat resistance, turbo protection, and stability under stress.

---

✅ Very Tuned (Track or Over 500 HP Builds)

If your V35A-FTS is on the cutting edge:

• Recommended Grade: SAE 10W-60 or Racing 5W-50

Top Oils:

• Motul 300V Competition 15W-50
• Red Line 10W-60 High Performance
• Amsoil DOMINATOR 15W-50
• Royal Purple XPR 10W-60

These oils are designed for racing and heavy driving applications. They reduce breakdown under heat and protect internal components during hard driving.

5. Maintenance Tips for Tuned V35A-FTS

Maintenance is the secret to engine life, whether stock or tuned. Here’s a good habit to follow:

🛠️ Must-Have Maintenance Habits:

• Oil change every 3,000–5,000 miles (tuned) or 5,000–10,000 miles (OEM)
• Warm up engine before hard driving
• Let turbos cool down after driving before shutdown
• Replace oil filter every oil change (use high-flow filters)
• Inspect PCV system, oil catch cans, and crankcase ventilation
• Use high-octane fuel (91 AKI or 95 RON) for tuned builds
• Monitor boost pressures, AFRs, and oil pressure with gauges or digital dash

---

6. Oil Change Intervals and What to Watch Out For

Build Type	Recommended Oil Change Interval
OEM Stock	5,000–10,000 miles (8,000–16,000 km)
Mild Tune	3,000–5,000 miles (5,000–8,000 km)
Track / Race	Every 2,000–3,000 miles

🔍 Watch:

• Oil color (don’t expect it to turn black too fast)
• Oil level (V35A-FTS will consume oil on heavy use)
• Strange smells (fuel dilution)
• Oil in coolant or coolant in oil

7. Warning Signs Your Engine Oil Needs Changing

Ignoring oil condition can lead to serious damage. Look out for:

• Noisy or rough engine
• Turbo whine or reduced boost
• Oil pressure warning light
• Burning oil smell
• Bad fuel economy
• Dirty or gritty dipstick oil

Always use a quality oil filter (e.g., Mobil 1, Toyota OEM, K&N) and replace it with each oil change.
