Hello all,
Vehicle described in the title, also in my sig. Currently has 208K on it. Runs flawlessly. Uses/loses very little oil. May have to add half a quart over an OCI which is currently about 3K/5-6 months. I work 4-5 days a week, round trip of about 32 miles, 85% of which is highway at 55+. Otherwise its city driving, so 30-45 and occasional short trips to the grocery store. Id sat I put on between 130-160 miles per week, depending.
Wondering about what I should go to for an OCI. Imm sure I can go a good bit longer than the 3K OCI I am doing right now. Ive been considering switching to 5K OCI and changing it once a year, maybe twice. Ive been stocking up on HDEO, mostly Rotella. A mix of T4 10w-30, 15w-40, T5 15w-40, and T6 5w-40 and 15w-40. IT just depends on what I could find where, and for what price. From what Ive read on here over time, any one of those could easily handle a 5k OCI, even the T4 conventional which from what I understand is actually more of a syn blend than a straight conventional.
I plan on running the 15w-40 during the summer, and during the winter thinned with 10-20% MMO if need be.
I just want to know if a 5k OCI is acceptable for this engine, or if I could even maybe go even longer than that. I plan on sending a sample to blackstone with my next oil change. My driving style is spirited, with the occasional WOT up to highway speed.
