Round 3 covered Motul 300V for the engine. This post stays on transmission and axle fluid\u2014where the wrong bottle can chatter an LSD, wear syncros, or leave a hypoid gear under-protected on a hot weekend.<\/p>\n\n      <p>Both Gear 300 and Gear 300 LS are Motul ESTER Core\u00ae 75W-90 racing lubricants with API GL-4 \/ GL-5 language on the current technical data sheets. The difference that matters is limited-slip friction modification. Gear 300 is Motul's pick for gearboxes and hypoid diffs <strong>without<\/strong> limited-slip systems. Gear 300 LS adds a dedicated friction modifier for clutch-type LSDs. This guide sticks to Motul's TDS wording, explains where Gear Competition 75W-140 and Motul 90 PA sit, and keeps DCT fluid out of the wrong fill.<\/p>\n\n      <div class=\"callout\">\n        <strong>Shop Motul gear oils at Track Ready Products:<\/strong> Gear 300, Gear 300 LS, Gear Competition \/ FF Comp 75W-140, 90 PA, and Motul DCT fluids. <a href=\"https:\/\/www.trackreadyproducts.com\/motul-m-6.html\">Browse Motul<\/a> \u00b7 <a href=\"https:\/\/www.trackreadyproducts.com\/gear-oils-c-696_697\/\">Browse gear oils<\/a>\n      <\/div>\n\n\n      <!-- Section 1 -->\n\n      <h2 id=\"gearbox-vs-diff\">Gearbox Oil vs Differential Oil<\/h2>\n\n      <p>A manual gearbox and a differential can share a housing (transaxle) or live in separate cases. Either way, the fluid has to:<\/p>\n\n      <ul class=\"go-list\">\n        <li>Protect gears under shock load and high temperature<\/li>\n        <li>Let synchronizers (or dog rings) do their job<\/li>\n        <li>Match clutch-pack friction in a limited-slip differential when one is present<\/li>\n      <\/ul>\n\n      <p>Put a non-LS gear oil in a clutch-type LSD that needs friction modification and you can get chatter, grab or poor lockup. Put a heavily friction-modified LS oil where Motul or the OEM says not to, and you can upset syncro feel or electronic LSD behavior. Motul's TDS sheets draw that line clearly\u2014follow them, not a forum \"I run X in everything\" post.<\/p>\n\n      <p>DCT and DSG cars are a separate story. They need dual-clutch fluid (Motul High Performance DCT Fluid or Multi DCTF where specified), not Gear 300.

If you have a clutch-type LSD that needs friction modification, Motul's Gear 300 LS is the 75W-90 ester bottle with the dedicated friction modifier. Confirm on Motul's chart and your owner's manual.<\/p>\n\n      <h3>Can I use Gear 300 in an LSD?<\/h3>\n\n      <p>Motul positions Gear 300 for hypoid differentials <strong>without<\/strong> limited-slip systems. A clutch-type LSD that needs LS additive is the Gear 300 LS (or Gear Competition 75W-140) path. Using the non-LS oil in an LSD that needs friction modification is how chatter and grab show up.<\/p>\n\n      <h3>Motul Gear 300 vs Red Line?<\/h3>\n\n      <p>Both brands sell high-performance gear oils; this post stays on Motul TDS numbers we have on hand. Compare Red Line's published TDS for the exact viscosity and LS\/non-LS product against Motul's sheets and your OEM spec\u2014do not treat \"track brand\" as a substitute for GL rating and LS friction needs.<\/p>\n\n      <h3>How often should I change diff fluid after track days?<\/h3>\n\n      <p>Motul says follow the manufacturer and adjust to your use. Hot HPDE weekends usually mean shorter intervals than street bumper-sticker schedules. Inspect fluid after hard events; change sooner if it smells burnt or the LSD behavior changes.<\/p>\n\n      <h3>Is Motul 90 PA still relevant?<\/h3>\n\n      <p>Yes as a Motul EP mineral LSD lubricant still published and stocked, especially for older or Motul-specified LS axles. For many modern BMW LS rear axles Motul itself points to Hypo Synt LS 75W-140 or Gear Competition 75W-140 instead. Read the application, not nostalgia.<\/p>\n\n      <h3>Can I put Gear 300 in a DCT?<\/h3>\n\n      <p>No. DCT \/ DSG units need dual-clutch fluid (Motul High Performance DCT Fluid or Multi DCTF where specified). Gear 300 and Gear 300 LS are hypoid\/gearbox gear oils. Ignore any store-title \"DSG\" wording that conflicts with Motul's TDS.<\/p>\n\n\n      <hr class=\"section-rule\">\n\n      <div class=\"cta-block\">\n        <h3>Shop Motul Gear 300 and Gear 300 LS at Track Ready Products<\/h3>\n        <p>Shop Motul Gear 300 \/ 300 LS \/ Gear Competition, or text us gearbox vs diff + vehicle at <strong>(949) 954-3322<\/strong> and we will help you pick the right bottle.<\/p>\n        <div class=\"cta-actions\">\n          <a href=\"https:\/\/www.trackreadyproducts.com\/motul-m-6.html\">Browse Motul<\/a>\n          <a href=\"https:\/\/www.trackreadyproducts.com\/gear-oils-c-696_697\/\" class=\"secondary\">Browse gear oils<\/a>\n        <\/div>\n      <\/div>\n\n    <\/article>\n\n    <!-- SIDEBAR -->\n    <aside class=\"go-sidebar\" aria-label=\"Article navigation and related links\">\n      <div class=\"sidebar-sticky\">\n\n        <div class=\"sidebar-widget\">\n          <div class=\"widget-head\">Navigation<\/div>\n          <div class=\"widget-body\">\n            <a href=\"https:\/\/www.trackreadyproducts.com\/garage\/\" class=\"back-link\">Back to the Garage home<\/a>\n          <\/div>\n        <\/div>\n\n        <a href=\"https:\/\/www.trackreadyproducts.com\/motul-m-6.html\" class=\"sidebar-cta-btn\">Shop Motul<\/a>\n\n        <div class=\"sidebar-widget\">\n          <div class=\"widget-head\">At a Glance<\/div>\n          <div class=\"widget-body\">\n            <div class=\"sidebar-stat-item\"><span class=\"s-label\">Non-LS pick<\/span><span class=\"s-val\">Motul Gear 300 75W-90<\/span><\/div>\n            <div class=\"sidebar-stat-item\"><span class=\"s-label\">Clutch LSD pick<\/span><span class=\"s-val\">Motul Gear 300 LS<\/span><\/div>\n            <div class=\"sidebar-stat-item\"><span class=\"s-label\">75W-140 LS ester<\/span><span class=\"s-val\">Gear Competition (FF Comp)<\/span><\/div>\n            <div class=\"sidebar-stat-item\"><span class=\"s-label\">DCT cars<\/span><span class=\"s-val\">Motul DCT fluid \u2014 not Gear 300<\/span><\/div>\n          <\/div>\n        <\/div>\n\n        <nav class=\"sidebar-widget\" aria-label=\"In this article\">\n          <div class=\"widget-head\">In This Article<\/div>\n          <div class=\"widget-body\">\n            <ul class=\"toc-list\">\n              <li><a href=\"#gearbox-vs-diff\">Gearbox vs Diff<\/a><\/li>\n              <li><a href=\"#gear-300\">Gear 300<\/a><\/li>\n              <li><a href=\"#gear-300-ls\">Gear 300 LS<\/a><\/li>\n              <li><a href=\"#side-by-side\">Side-by-Side<\/a><\/li>\n              <li><a href=\"#which-hardware\">Hardware Match<\/a><\/li>\n              <li><a href=\"#change-intervals\">Change Intervals<\/a><\/li>\n              <li><a href=\"#which-to-buy\">Which to Buy<\/a><\/li>\n              <li><a href=\"#faq\">FAQ<\/a><\/li>\n            <\/ul>\n          <\/div>\n        <\/nav>\n\n        <div class=\"sidebar-widget\">\n          <div class=\"widget-head\">Related Articles<\/div>\n          <div class=\"widget-body\">\n            <div class=\"related-post\">\n              <div class=\"r-tag\">Tech Guide<\/div>\n              <a href=\"https:\/\/www.trackreadyproducts.com\/garage\/best-oil-for-track-days-motul-300v-competition-vs-street-oils\/\">Best Oil for Track Days (Motul 300V)<\/a>\n            <\/div>\n            <div class=\"related-post\">\n              <div class=\"r-tag\">Tech Guide<\/div>\n              <a href=\"https:\/\/www.trackreadyproducts.com\/garage\/dct-cooler-for-track-days\/\">DCT Cooler for Track Days<\/a>\n            <\/div>\n            <div class=\"related-post\">\n              <div class=\"r-tag\">Tech Guide<\/div>\n              <a href=\"https:\/\/www.trackreadyproducts.com\/garage\/oil-cooler-for-track-days\/\">Oil Cooler for Track Days<\/a>\n            <\/div>\n            <div class=\"related-post\">\n              <div class=\"r-tag\">How-To<\/div>\n              <a href=\"https:\/\/www.trackreadyproducts.com\/garage\/preparing-for-track-day\/\">Preparing for Track Day<\/a>\n            <\/div>\n            <div class=\"related-post\">\n              <div class=\"r-tag\">Track Guide<\/div>\n              <a href=\"https:\/\/www.trackreadyproducts.com\/garage\/street-car-to-track-car-the-real-order-of-operations\/\">Street Car to Track Car<\/a>\n            <\/div>\n          <\/div>\n        <\/div>\n\n      <\/div>\n    <\/aside>\n\n  <\/div><!-- .go-page-wrap -->\n<\/div><!-- .go-post -->\n","protected":false},"excerpt":{"rendered":"<p>Motul Gear 300 vs Gear 300 LS is the gearbox-and-diff question that shows up right after you settle engine oil.
