Hi. I have been asking the same question but with regard to all lubricants.

The car has done 106,000 miles and we were seeking advice on the grades of lubricants to use.

The engine is B18B and the car manual recommends SAE 10W-30 oil, however given the age and mileage of the car we thought this might be a little thin. Liqui Moly recommends SAE 20W-50HD. We are based in Scotland so temperatures vary from probably -15°C to +30°C.

The transmission is an M41 and again the car manual recommends SAE 20W-40. However Liqui Moly recommends SAE 20W-50HD, the same as the engine oil, or Touring High Tech HD30.

Finally the rear axle with slip differential. This has a bit of a rumble on it and the car manual recommends American military standard MIL-L-2105 or MIL-L-2105 B. Liqui Moly recommends Hypoid Gear Oil.

Any guidance or advice you could give on these three lubricants would be very much appreciated.

Thanks
