It is said that ester fully synthetic motor oil is good, but what is the advantage? Ester oil is a kind of high-end synthetic lubricating oil that is very popular now. It was developed by the Germans during World War II to solve the problem of starting tanks and locomotives in the cold zone. Later, it was widely used in aviation and other fields. Gradually switch to motor sports. Ester base oils are formed by catalytic dehydration of organic acids and alcohols. Commonly used are diester, polyol ester and compound ester. Ester products contain various forms of oxygen atoms such as carbonyl oxygen and alcohol oxygen, which are functional groups that distinguish ester synthetic oils from general mineral oils, and are polar. The base oils of the three types of synthetic oils and PAO synthetic oils do not contain such groups. In the lubrication process, the ability to form a thick oil film between the friction pairs is critical to the lubrication effect, and compounds containing polar groups are more likely to be adsorbed on the friction interface to form an effective tough oil film. The same function, non-polar synthetic oil is achieved by adding additives. From the product description, you can see words such as diester, alcohol ester, etc. In fact, the synthesis raw materials are different, and the reaction mechanism is similar. Ester fully synthetic motor oil, where is it stronger? Everything has two sides, and ester oils are no exception. Let’s talk about the advantages first: Advantages of Ester Synthetic Motor Oils 1. Good thermal stability. From the perspective of thermal decomposition temperature, diester oils are generally around 280 degrees, and alcohol esters are more than 300 degrees. This is related to its molecular structure. The fully hindered ester esterified with neopentyl polyol has a higher decomposition temperature. 2. The polar structure gives this kind of oil special lubricating performance, and it is easy to adsorb on the interface to form a stable oil film. Even if it is cold, it will not return completely, providing good low temperature protection. For example, compared with mineral oil lubricating oil, the polar functional group of ester group is sucked on the friction pair interface like the sucker of gecko, and it is not easy to fall off even under the condition of low temperature and cold car. 3. Strong sensitivity to additives. It can be well integrated and synergistic with additives such as antioxidant and anti-wear. Disadvantages of synthetic ester oil The biggest disadvantage of ester oils is their hydrolytic stability and material compatibility. Because of the polar group, ester oil is easy to absorb moisture (remember to tighten the cap when you use the rest). The stability of polyester to pure water is not bad, and it is unstable in acid and alkali environment. Since the engine oil contains many additives containing phosphorus and sulfur, and there will be fine metal particles worn down during the working process, the additives will produce acidic substances under the metal catalysis, which further catalyzes the hydrolysis of the ester. Ester will obviously swell rubber products of certain structures, which is also one of its disadvantages. However, these disadvantages are alleviated by appropriate modifying additives. What is the difference between ester synthetic oils? Ester synthetic oil contains various forms of oxygen atoms such as carbonyl oxygen and alcohol oxygen, which makes ester synthetic oil different from the functional group of general mineral oil and has polarity; while the base oils of three types of synthetic oil and PAO synthetic oil are not Contains this group, which is the biggest difference between lipid synthetic oil and ordinary synthetic oil. Active adsorption oil film and passive adhesion oil film During the lubrication process, the formation of a thick oil film between the friction points of the lubricating oil is critical to the lubrication effect. Compounds containing polar groups are more likely to be adsorbed on the friction interface to form an effective tough oil film. The same function, non-polar synthetic oil is achieved by adding additives. Mainly rely on a certain viscosity to adhere to the friction interface. When the engine stops working, this adhesion gradually flows back and falls off under the action of gravity, and the oil film becomes very fragile. The oil film produced by chemipolar adsorption can be maintained for a long time after the engine is stopped, providing uninterrupted lubrication for the engine.
For the new supra the 5w40 synthetic with ester would be the best protection at the race track. The 0w30 for street. I would not run the 0w20. To thin not protection for turbo.
ちょうど自分が使ってる好きなオイル2種の比較動画でとても良かったです。やっぱりスノコはいい感じですね
実はこのテスト、オイル屋がよくやるんです。
我々一般人が普段使いするならどの様な物を選べば良いかのテストに最適なのが「コレ」なんです。
この結果から普段使いするならどちらが最適か………ちょっと考えればわかるはず（爆）
オイルは「有名だからーー」で選ぶと痛い目見ます。まさに「コレ」（爆）
動画主さん！いい仕事してると思います！
スラッジがどれだけ出るかに興味があったのでやってみたら・・・という感じです。
素晴らしい実験です！
86でGRオイル使ってサーキット街乗りしますが、確かにレスポンスが向上してることを体感してます。
初めは0W-20で大丈夫か不安でしたが車も全く問題なしで冬場でも使えるのがありがたい。
周りの知人も揃ってGRオイル一択と言ってますね。流石トヨタがガチで作った高級オイルだけはあります。
GRはエンジン始動直後からのレスポンスは良かったです。
油温も低い傾向だった気がします。オイルの戻りが早いからでしょうかね。
GRオイル(0w-30)は結構な量の添加剤が入ってそうですね。
スラッジは熱を加えることで酸化した鉱物ですからね。
5000キロ交換推奨のようなので、メーカーもわかっているんでしょうね。
ポリマーテクノロジーが売りなので、粘度指数向上剤はたっぷり入れて性能を稼いでいるんでしょうね。

実際、GRオイル使ったとのない自分が言うのもあれですが、
スノコ好きな自分からすると公道用途なら圧倒的にスノコでしょうね。
スノコのオイルは、圧倒的にブローバイの発生が少ないでブローバイ再燃焼での
燃焼室へのカーボン堆積量が非常に少なくエンジンが痛み難い上にオイル自体がロングライフ。
一般的に低粘度・低フリクションを謳うオイルは、ブローバイのシリンダー吹き抜け量が多く
ブローバイにオイルミストを多く含み易くなり再燃焼時、燃え残りのカーボンが燃焼室に溜まりやすいです。
しかもクランクケース内が高温ガスに晒される影響でエンジンオイルの劣化も早いです。コスパが悪い。
エンジンを頻繁に開けるサーキットやレース用途のエンジンの場合、上の回転が伸びるので良いのですが。
私も同じような認識です。
スノコはコスパ的にも優れているオイルだと思っています。
ワコーズとかモチュールとかtakumiとかの方がメジャーなんですかね？
@@kurumanalife
理由は、簡単ですよ。
ワコーズやモチュールなどのレーシングオイルは、新油に入れ替えた直後のエンジンの吹け上がり向上が体感し易い。
特にエンジン＆ミッションの潤滑をエンジンオイルで兼用する二輪車の場合、変速操作にも潤滑性向上が顕著に現れます。
新油に入れ替え暖機を行った直後にシャシダイで出力測定するといきなり最高出力を出せる特性で新油効果が分かり易い。
逆に言うと粘性によるフリクションロスを抑え交換直後の出力重視な特性によりブローバイ量が多く油温も上がり易いのでオイル劣化し易い。
エンジンを開ける頻度が少ないストリートユースでは、ブローバイ油分による燃焼室のカーボン堆積が進行し易いオイル特性。
短いサイクルでのオイル交換前提で使用しないとブローバイに含まれる油分でカーボン堆積と言う悪影響が顕著に出やすいです。
スノコのエステルベースレーシングオイルは、密閉性重視＆熱ダレ抑制重視で劣化が少ない分、新油入れ替え直後が体感し難いのです。
レーシングオイルを謳っているにも関わらずストリートユースで長期間入れっ放しでも明らかに劣化か少ないからです。落差が少ない。
ピストン密閉性が長期に渡り続く為、ブローバイ量が非常に少ない期間が持続するため燃焼室やケース内のカーボン堆積が極僅か。
実際レースに使うと油温の上がるレース中盤～後半にかけ熱ダレし難くストレートも伸びてくので勝負を仕掛けられる特性とのこと。
メーカー側からすると交換頻度が下がり絶対販売量が減るわけで商売的に旨味が少ないでしょうがストリートユーザーにとってありがたい特性。
オイルライフやエンジン保全の観点でサーキットユース以外のストリートユースメインのユーザーにもメリットが大きいオイルと思ってます。
どっちも同じ工場で作っているとしたらどう思う？w
そんな事実が！？
添加剤で性能が変わるってことですかね。
@@kurumanalife 国内製造所は数カ所しかないからみんなそこのOEMですよ
それぞれのメーカーのオーダーで作っている感じ
例えばSUNOCO（サン石油）の市川の工場は工程の撹拌技術が良いという話をきいたことがあります
基本的にスチール缶は国内、プラボトルは海外という感じ（違うケースもある)
@@SNS-lo8hw 別に同じ店でロースも上ロースも食えるしなぁ、同じ養豚場で品種を分けて飼育してるしなぁ
だからなにとしか言いようがない、なんの中身もない匂わせ
ロータリーエンジン搭載車に乗ってますが燃焼室のスラッジが気になります！
色々なオイルの燃焼実験して頂ければ今後のエンジンオイルを選びやすいです！
シリーズ化して頂きたいです！
この動画を観て今のところsvelt5w-30次回は入れようかと思います！
オイルのストックもあるので、あれこれ試すのは難しいですが、一つ気になっているオイルがあるので、次のオイル交換のタイミングで実験するかもしれません。
SUNOCOはRE雨宮の雨さんも推していたので良いと思います。
………ってコメしちゃったんですけど、他のオイルテスト動画見ました。
最後までキッチリ燃やしきっちゃって下さい（笑）
１度発火して消えて→また発火させて消えて→を繰り返してください（笑）
編集の関係でカットしていたのであればごめんなさい。
……でもそこがこのテストの「ミソ」なんスよ（笑）
家の前でやって、煙もすごいのですぐに消化してしまいました。
燃やし尽くすとどうなるかは何となく想像がつきますね。
