for both mineral or synthetic engine and gear oil, wala naman kelangan na adjustments. you just need to replace seals as they start leaking. but they will leak regardless of whether you use mineral or synthetic oil.
Sir Speedyfix, good day! pwedi po ba ang engine oil na 15W40 para sa manual transmission ng Crosswind XL 2010 model? TIA.
nope you can't use that. you need to use a 75w90 or 80w90 gear oil for that.
What semi-syhtetic oil grade and manual transmission oil do I need for my Toyota REvo 7-KE Gas M/T? Thanks
