What is 15W 50 oil used for?
15W-50 motor oils 15W-50 has historically been a viscosity recommended for high performance engines, and is used today primarily in motorsports racing where engines are stressed due to high revving and heat.
Is synthetic oil OK for flat tappet cam?
AMO 10W-40 and ARO 20W-50 Synthetic Premium Protection oils are recommended for flat-tappet and late-model high-performance motors.
Is Mobil 1 high in zinc?
With double the zinc* level of current low-viscosity, API-approved passenger car oils, Mobil 1 Racing oils form a protective sacrificial layer on steel surfaces to protect against engine wear during metal-to-metal contact.
Which is better 15w-40 or 15w50?
The answer is no. 15w-50 is a more suitable engine oil for your Royal Enfield than 15w-40. As 15w-50 is the recommended viscosity grade for the Twin Spark engines that are used in their models. Both have the same viscosity but 15w-50 is more resistant to higher temperatures than 15w-40.
Is 10W40 better than 15w50?
At low temperature the 10W oil will flow better than a 15W oil. So the 15W-50 oil is “thicker” at cold temperatures than the 10W-40, therefore it will flow worse on start up; but being a little “thicker” it and maintains its viscosity at high temperatures better than the 10W-40.
What oil should I use with a flat tappet cam?
How much zinc is in Shell Rotella 15w40?

Can I use 15w50 instead of 15W-40?
What is the difference between 15W-40 and 15w50?
What is the difference between 15w40 and 15w50? 15w-50 as an engine oil lubricant is slightly more viscous in viscosity as opposed to 15w-40. As mentioned above, the oil is fit to provide good engine lubrication as well as great protection. Furthermore, the oil is also known to have a good drain interval.
