Absolutely right, once he make the clearances more he cannot come back plus most of the 10w30 oils in the market are having mineral based additives and despit claiming Group 2 they are mixture of Group 1 & 2 base oils... in the longer run the wear rate is more as compare to synthetic additives which comes in 0w30 / 5w30.
As being in business of Power Generators and Gas Engines in Oil & Gas sector we are very well connected with oil suppliers in the country so know the in and outs very well.
Total Parco is the official supplier to Honda Atlas so its a good oil they used to market their 10w30 before which was from Caltex but now they made it obsolete and focuses on 5w30 or 0w20.... At least one should be satisfied that he is not getting 2 nobry.
