This study is aimed to know the influence of price, substitution price, consumer income, and the number of vehicles toward the order of Pertamina lubricant in Banda Aceh. For the analysis purpose, multiple regression analysis is used.This research used time series data which was started from 1991 until 2015. The data was a secondary data taken from the Statistic Center Board of Pertamina, and from related institution as well as from various types of sources related to this research. The model used was Marshallian Linear Request function which was analyzed by multiple linear equations through Ordinary Least Square (OLS) approach.This research produced a satisfying result. This was seen from simultaneous and partial examination whereas all free variables in this research impacted significantly toward the order of the lubricant under Mesran trademark. Based on the estimation, price variable was resulting negative, meanwhile substitution price, consumer income and the number of vehicles were resulting positive toward the order of the lubricant of Mesran trademark. This result matched the existing theory. The 94,89 percent determinant coefficient (R2) means that free variable which consisted of variable of Mesran lubricant, substitution price, consumer income, and the number of vehicles were able explain the changes of the order of Mesran lubricant for approximately 94,89 percent, while the remaining 5,51 percent was explained by other variables, such as desire, model, and consumer income distribution, etc., which were excluded of this research model.Pertamina should keep enough supply of lubricant to maintain its normal price in Banda Aceh.Artikel ini bertujuan adalah untuk mengetahui pengaruh harga, harga pengganti, pendapatan dan jumlah kendaraan terhadap permintaan pelumas pertamina di Kota Banda Aceh. Dalam Analisisnya digunakan analisis regresi linear berganda (Multiple Regressions).Penelitian ini menggunakan data time series dimulai dari tahun 1991 sampai dengan 2015. Jenis data adalah data sekunder yang diperoleh dari Badan Pusat Statistik, Pertamina, , dan intansi terkait lainnya serta dari berbagai sumber dan literatur lain yang ada kaitannya dengan penelitian ini. Model yang digunakan adalah fungsi Permintaan Linear Marshallian, dianalisis dengan dengan persamaan linear berganda melalui pendekatan OLS (Ordinary Least Square).Hasil estimasi menunjukkan hasil yang memuaskan ini terlihat baik dari pengujian secara simultan maupun secara partial, dimana semua variabel bebas dalam penelitian ini berpengaruh signifikan terhadap permintaan pelumas merek mesran. Berdasarkan hasil estimasi variabel harga berpengaruh negatif dan harga pengganti, pendapatan dan jumlah kendaraan berpengaruh positif terhadap permintaan pelumas merek mesran, hal ini sesuai dengan teori. Koefisien determinan adjusted (R2 ) sebesar 94,89 persen yang artinya variabel bebas yang terdiri dari variabel harga pelumas merek Mesran, harga pengganti, pendapatan dan jumlah kendaraan mampu menjelaskan variasi perubahan permintaan minyak pelumas merek Mesran sebesar 94,49 persen dan sisanya sebesar 5,51 persen dijelaskan oleh variabel lainnya diluar model penelitian ini seperti selera, corak dan distribusi pendapatan dalam masyarakat dan lain- lain.Pertamina harus mengupayakan suplai pelumas di Kota Banda Aceh selalu tersedia cukup, hal ini dilakukan untuk menjaga kestabilan harga pelumas itu sendiri.
