1GR-FE расчитан и работает на REGULARe - это пиндосский 87 (91 октан по исследовательскому), и наш Аи 92 (92октан по исследовательскому)
Руководство по эксплуатации немного о другом говорит, насколько я помню.
Просто считаю, раз уж призывать соблюдать рекомендации производителя по маслу, то и по бензину тоже не мешало бы.
The
1GR-FE is the 4.0 L (3956 cc) version, designed for longitudinal mounting in RWD and 4WD pickup applications. It has a 94 mm bore and a stroke of 95 mm. Output is
236 hp (176 kW) at 5200 rpm with 266 lb·ft (361 N·m) of torque at 4000 rpm on
87 octane, and
239 hp (178 kW) at 5200 rpm with 278 lb·ft (377 N·m) at 3700 rpm on
91 octane. This engine features Toyota's VVT-i, variable valve timing system on the intake cam and a
compression ratio of 10.0:1. Service weight, including fluids, is 166 kg (366 lb).
An updated version of this engine features Dual VVT-i, increasing output to
254 hp (189 kW) and 270 lb·ft (366 N·m) on
87 octane and
285 hp (213 kW) and 289 lb·ft (392 N·m) on
91 octane. Inside, the 1GR uses a "taper-squish" combustion chamber design with matching pistons to improve anti-knocking and engine performance, while also improving intake and fuel efficiency. Toyota adopted a siamese-type intake port, which reduces the surface area of the port walls and prevents fuel from adhering to such walls. This engine has special cast-iron cylinder liners cast into the block, which are a spiny type to improve adhesion between the liner and cylinder block. With these special thin liners it is impossible to bore the block. In the event of cylinder wall damage (scoring, deep protrusions, etc.), the entire cylinder block must be replaced. For increased block rigidity, the 1GR also receives a high temperature plastic insulator/protector, which fills the empty space between the outer portion of the cylinders and block material common to open deck engines. For increased cooling efficiency, the 1GR employs water passages between the bores of the engine. There are two such passages for each bank for a total of four. This reduces cylinder hot-spotting and keeps combustion chamber temperatures more uniform.
