\"Oil<\/figure>\n<\/p>\n

<\/p>\n

SAE (Society of Automotive Engineers) Grades<\/h2>\n

10w =<\/strong> This is a grade for the weight (or thickness) of the oil<\/a> at colder (‘winter’) temperatures.
\nTo get this grade, the weight of the oil<\/a> is tested at 0°F<\/p>\n

40 =<\/strong> This is a grade for the weight (or thickness) of the oil<\/a> at hotter temperatures. To get this grade, the weight of the oil<\/a> is tested at 200°F<\/p>\n

Please note – <\/strong>The example used (10w40<\/a>), can also be shown as 10\/40 and 10w-40. These are all the same grade (it’s just some people prefer to write it differently!)<\/p>\n\n\n\n
Number<\/strong><\/td>\n\n

10w<\/h2>\n<\/td>\n

\n

40<\/h2>\n<\/td>\n<\/tr>\n

Meaning<\/strong><\/td>\nDefines the viscosity (thickness) of the oil<\/a> at it’s coldest operating temperatures.
\nThis first number is used to show the viscosity of the oil<\/a> used in an engine during winter when starting the vehicle from cold. The ‘w’ stands for ‘winter’.
\nDifferent countries often require different grades of oil<\/a>, depending on how warm or cold the winters are. e.g. 10w40<\/a> is often used in the U.K, where as a country that has harsher or colder winter might use a 5w40 weight oil. The oil viscosity or weight for cold temperatures is tested at 0°F. Generally speaking, the higher the number, the thicker the oil<\/td>\n		This is the number or grade that defines the oils<\/a> viscosity or thickness at higher operating temperatures.
\nThe oil<\/a> viscosity or weight for hot temperatures is tested at 200°F.<\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":false,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2},"jetpack_post_was_ever_published":false},"categories":[2],"tags":[13,14,15,12],"class_list":["post-25","post","type-post","status-publish","format-standard","hentry","category-oil-info","tag-10w40","tag-oil-viscosity","tag-sae","tag-what-it-means"],"yoast_head":"\nMotorcycle oil viscosity -
