*: If 5W-30 synthetic oil is not available, 5W-40 conventional oil may be used if replenishment is needed but should be changed to 5W-30 synthetic oil at the next oil change. Conventional oil may be used if synthetic oil is unavailable. and applicable temperatureĥW-30 synthetic oil is the required oil for optimum engine performance and protection. ![]() With only a 2.8 TBN remaining I'm not sure I buy this oil being good for. Car is (and will remain) bone stock aside from having the noise pipe removed. Break-in oil was changed out at 1k miles, with subsequent changes at 3k, 6k, then again at 9k. ILSAC (International Lubricant Specification Advisory Committee) GF-5, which can be identified with the ILSAC certification mark (Starburst mark) 3rd run on Motul X-Clean 5w30, I'm using a 5w30 in an attempt to keep Subaru happy under warranty. When adding oil, you may use different brands together as long as they are the same API classification and SAE viscosity as those recommended by SUBARU.ĪPI (American Petroleum Institute) classification SN with the words “RESOURCE CONSERVING”.The following table lists the recommended viscosities and applicable temperatures. However, in hot weather, oil of higher viscosity is required to properly lubricate the engine. Oils of lower viscosity provide better fuel economy. In choosing an oil, you want the proper quality and viscosity, as well as one that will enhance fuel economy.The necessary quantity for replacement may differ slightly depending on the temperature and other factors. Each quantity indicated here is only a guideline.If the SUBARU approved oil is unavailable, the following alternative oil can be used. If the approved engine oil is unavailable, use the alternative engine oil described on the next page. For further details, please contact your SUBARU dealer. Keep in mind the temp chart in your manual shows 5W-40 and mentions that thicker viscosity is required in high temps.Īlways use the SUBARU approved engine oil. Probably the best specs on paper of all GF5 oils. An exception may be Ravenol but there’s not much data on it. Yeah, running any GF5 oil is pretty much the same. It should have a bit more ZDDP than Xclean or Rotella MV. It meets most of the same specs that xW-40’s make with the exception of Porsche A40. I haven’t seen a voa on it but Castrol Edge ACEA A3 5W-30 might be a good choice. Don’t push the oil change intervals beyond 4-5k though. Both of these oils have a high HTHS so they will stay in grade better than GF5 oils and are cat friendly. The new Shell Rotella T6 5W-30 MV is another good choice if you’re looking for lower ZDDP oils like the reduced SAPS Xclean. Xclean is a reduced SAPS oil is which is why it’s good for DI as reduced SAPS oils are good at mitigating intake valve deposits. The original X-Clean is probably still available at retailers until their stock and their distributor's stock runs out. They should all be more shear stable than a GF5 oil and the difference in the three is likely anti-wear additive levels. Instead of saying “oil is oil” I prefer to say specs are specs. X-Clean+ is also one of the new ones along with EFE and FE. Any other ideas of something 5W30 that is better than Subaru oil? I was going to to pick up Motul Xclean, but was told that this is better for DIT motors. I am still under warranty and wanted to stick to a 5W30. So wanted to know what you guys currently use for your Sti? BMW had few years back TIS that LL01 proved to be much more suitable for N63 engines in Europe, than in the US where they see mostly city cycle.I know this topic has been posted over and over, but different oils are discontinued yearly, or the compounds change. Primary decision behind this is that different markets have different exploitation requirements. One can use LL)1 or LL01FE or LL-17FE etc. All of the recent BMW's require LL01FE or LL-17FE.Īll BMW new engines are approved for LL01 and FE oils. So, which 2019MY+ BMW's require LL-01? That is the baffling part to me. Compared to the existing products, both gen2 products have higher shear stability, longer oil life, and enhanced piston deposit control to avoid LSPI." ![]() "No compromises were made as the new OEM tests required a stronger additive package to maintain the BMW approval for 2019+ or receive new approvals from Porsche/VW (in the case of X-clean). "Our primary reason for reformulating was due to new standards from BMW to meet their improved LL-01 and LL-04 standards on 2019+ vehicles, but it also gave us a chance to achieve the new Porsche C40 approval on our X-clean 5W40 gen2 product."
