| 1212342 | 2011-06-27 03:14:00 | Ta for the replies. I agree (from what I've heard) that Honda engined machines are great. But... I've had three Briggs & Stratton engined machines over the years and they've all been wonderful. And of course the machine I have is in fact a B & G so I'm not going out to buy a bloody new Honda machine right now! But, as per my question, and what I suspected, any cheap engine oil should do. Thanks again. |

| 1212347 | 2011-06-27 06:40:00 | Multigrade car oil is great for cars, B & S, and most other small air-cooled motors thrive on straight 30 mineral oil. People who use other oil deserve the results they get, and should be forced to own Fords. ;) | R2x1 (4628) | ||
| 1212348 | 2011-06-27 07:03:00 | www.briggsandstratton.com Oil Recommendations/ "Oil Recommendation SAE 30 40° F and higher (5° C and higher) is good for all purpose use above 40° F, use below 40° F will cause hard starting. 10W-30 0 to 100° F (-18 to 38° C) is better for varying temperature conditions. This grade of oil improves cold weather starting, but may increase oil consumption at 80° F(27° C) or higher. Synthetic 5W-30 -20 to 120° F (-30 to 40° C) provides the best protection at all temperatures as well as improved starting with less oil consumption. 5W-30 40° F and below (5° C and below) is recommended for winter use, and works best in cold conditions." |

| 1212349 | 2011-06-27 09:56:00 | There is also the school of thought that says because the B&S engines are made down to a price and have crappy bearing material combinations, as pointed out by Prefect, the higher "lubricity" of a straight mineral oil will be more satisfactory than a lower lubricity multigrade oil which is up to about 50% viscosity improver (methylmethacrylate). Royal Enfield produced a similar crappy big end design with their big twins, running aluminium alloy con-rods direct on the crankpin with no bearing shell. I think it was the 'Constellation' that started the rot. Such a combination is poor because the alloy big end has no capability to embed particles unlike a conventional bearing shell. The slightest "pick-up" due to dirt and the progression to catastrophic big end failure is rapid followed by a mangled con-rod. I would think that a lubricity boundary lubrication additive like moly disulphide would be good in a B&S engine. |

I have found replacing oil regularly with a new filter at same time seems to the trick, 6 years and sweet as, as they say. |
